...Sample Hypothesis Testing Paper RES/342 Two-Sample Hypothesis Research Question A company decides to purchase homes to rent out to their employees. They have to decide if purchasing homes in a rural area is cheaper than purchasing homes from the inner city. 15 miles from the center of the city is inner city and anything passed 15 miles is rural area. The mean house pricing in the urban area is $232,736 out of a sample size of 59 with a standard deviation of $48,651. The mean house pricing in the rural area is $206,183 out of a sample size of 46 with a standard deviation of $40,896. At the 0.05 significance level, the company assumes that urban area is higher than rural area. Formulating a Verbal and Numeric Hypothesis To formulate a verbal and numerical hypothesis statement one must determine which type of two-sample statistic test the problem describes. The statement indicates that one would perform a right-tailed test. The words “is higher than” indicates that the alternate hypothesis will have the greater than sign in it. The statement also indicates that the standard deviation is known. Using this knowledge one may begin to formulate a verbal hypothesis. The researchers will test the hypothesis statement and try to find sufficient evidence to support the null hypothesis. If the evidence is insufficient one will reject the null hypothesis. If the evidence is sufficient one may fail to reject the null hypothesis. Simply put one is trying to figure out if the company...

...Hypothesis Identification Article Analysis Vanessa Redlinger RES 342 October 10, 2011 Roger Gibb Hypothesis Identification Article Analysis In an article entitled “The Teaching of Marketing Research in Relation to Industry Needs” from the Journal of Marketing, has a unique research question. The research question is how the subject matter of present marketing research courses compares with the type of work encountered in commercial research. The hypothesis was to find out what teachers were teaching in the classroom and find if it closely related to what those in the industry considered important and essential. The way this was accomplished was through having surveys completed by two groups – teachers and industry research personnel. Forty-six of the ninety teachers that received the survey responded. One hundred twenty-three of the two hundred seventy-seven of the industry research personnel responded. The survey questions were more open in nature, by not tying those surveyed to particular scenarios. Both groups were supplied with basically the same survey in which they ranked different items as essential, valuable but not essential, interesting buy not essential, or limited. Doing the survey in this manner helped remove any bias that might result from those being surveyed. The article also brought up an interesting side-note about one variable that was not considered in this particular survey. The ability of each individual teacher plays a large role in how students...

...Nonparametric Hypothesis Test:. Research can be focused in a number of ways, to help refine our topic to a point where we have clear hypotheses statements. If the housing industry was determined to be doing better than the rest of the economy, a hypothesis test might be in order, with mean prices greater than other housing industries. The test to determine the difference is the one sample run (Wald- Wolfowitz test to determine the mean prices to be equal to each home cost (Doane & Seward, 2007). However, March home sales were higher than expected. Our Presidents recent trip aboard has secured enough raw material and additional energy products to secure the USA zone of growth for 100 years. We believe America remains at the top of the economic world and by far the most secure in the housing industry recovery (Dohrmann B, 2011). More often than not, homeowners has maximize their time and search for the best sales for homes by searching information about homes sales and choices(Rosales L. 2011). The housing industry can also find the best buyer’s options that are available to him or her in a similar way that real estate agencies can seek the best sales on homes. However, the homes of the homeowners in the housing industry are set by the regional, state, and local expectations of the buyers and not so much by differences in qualifications of the homeowners. There are still a bright light in our housing futures across the nation (Rosales L, 2011) When the housing industry...

...The purpose of this paper is to review the hypothesis testing of the influence bank account balances have on ATM transactions. Team A will use a two-sample hypothesis test to compare two means to examine the hypothesis. The first part of the process will develop the hypothesis statement numerically and verbally. The test begins with the determination of the level of significance and decision rule whether to accept or not reject the null hypothesis. Calculating the test statistic will provide basis of the decision according to the critical region. The final section will describe the results in relation to the research question of bank account balance influencing the number of ATM transactions. Hypotheses Team A uses a five step hypothesis testing method as part of the research for this document in determining if two sample groups of bank account balances influence the number of ATM uses in one month. As with the steps for a one population hypothesis test, a two population hypothesis test follows the same sequence. Step one for Team A starts with stating the null hypothesis. Given the data shown in Appendix A and Appendix B, Team A has a hunch that bank account holders with larger balances tend to use ATMs more frequently than low account balance holders. Group A, from Appendix A, hold balances under $1600 for a given month and the Team measures the lower balance account’s ATM transactions during the given month. Group B samples include accounts with balances...

...researching a hypothesis, compare the means of two or more groups, and calculate the correlation between two variables. In this paper, Team C will explain the steps in researching a hypothesis; illustrate a comparison between the means of two or more groups, and make a calculation of the correlation between two variables. We will also reflect on the topics in week four that we are most comfortable with and the topics we struggled with at the same time. Additionally, we will explain how the topics relate to the applications within our personal or professional fields. Steps in Research Hypothesis In science class as children we were taught that a hypothesis was an educated guess, as we blossom into a more mature age we discover that it goes a bit deeper. A hypothesis can be used in different ways most of them in our daily lives. There are two types of statistical test you can perform. The null hypothesis’s that which represents the status quo to the party performing the sampling experiment—the hypothesis that will be accepted unless the data provide convincing evidence that it is false. The alternative, or research, hypothesis is that which will be accepted only if the data provide convincing evidence of its truth. In statistic, there are seven steps you need to perform to arrive at a statistical hypothesis. The first step is the null hypothesis in which you must state a fact until it is proven to be false. The alternative hypothesis is a rejection of the null hypothesis in which...

...MGMT600-1501A-03 Null and Alternative Hypothesis Instructor: Professor Dr. Throop, R. February 2, 2015 Null and Alternative Hypothesis A senior executive at Company W is having an issue understanding the concept of null and alternative hypothesis in the snack food research. In this paper, I will make it understandable for him to be able to see how this hypothesis’s work. Though it may be a little cryptic, the concept of null and alternative hypothesis is not very difficult. A null hypothesis is the speculation of a declaration that researchers hope to try to nullify or disprove. The alternative hypothesis is what the researcher actually believes to be the truth about the declaration (M.U.S.E, 2015). A hypothesis involves two types of statements: the null and alternative hypothesis. Statistical implication starts by identifying that research questions can be stated in conditions of a choice between two clear and mutually options. The only reason that null hypothesis and alternative hypothesis are different is chance. Let me break this down so that it will be easier to understand. I will break it down in a formula based statement in regards to the sack food industry. Let us look at this: A researcher must present a statement that is able to be proved or disproved. Once the expectation is known, then a counter statement is provided, which also known as the “null” hypothesis. We can represent this by using the term “H0” which means: H is the hypothesis and 0 is there is no difference...

...Nonparametric Hypothesis Testing RES/342 Nonparametric Hypothesis Testing During the course of the last three weeks, the team explored the hypothesis testing segment of statistics research. The first part of this assignment was the one sample hypothesis testing. The second was the two or more sample hypothesis testing, and finally in this third week, we will look at nonparametric hypothesis testing. This week’s project is a continuation of the previous projects and entails to build on the identical research question that we will frame a research hypothesis from the same provided data sets (Wage and Wage Earners) using ratio or interval numerical data; however, this week we will use a nonparametric hypothesis test to find our answer. In the next following paragraphs, the team will clearly affirm a hypothesis statement that will provide the base for our survey, perform a five-step hypothesis test on information concerning our choice and apply the concepts of nonparametric testing learned in this course, and describe how the results of our findings answer our research question. Finally, we will conclude this study with a brief summary that will examine the main points, the purpose, and conclusions of this final third week’s study on nonparametric testing. Perform the five-step hypothesis test on the data Nonparametric tests are statistical tests that analyze data that does not require assumptions about the distribution of shape of the population from which...

...Anxiety can be seen in our everyday life of balancing our jobs, our family, personal problems are in a growing need to upgrade yourself academically your studies can become a source of anxiety. Managing your time in order to meet your deadlines for test, discussion board with your fellow classmates or keeping up with dates for turning in papers all can create a level of anxiety for students. As a student, you are constantly balancing our anxiety levels and those can levels can build as we are preparing for test, because we anticipate what question may or may not be asked, om the test so it quiet normal to feel some anxiety sometimes during your academic career. Anxiety may even help motivate you and increase your performance or it could affect your academic performance. In this study we seek to examine the relationship between student’s anxiety for an exam and the number of hours studied. In statistic when we want to determine the relationship between the dependent and independent variable we are looking for a correlations according to Argosy (2014) correlation strictly determines whether a relationship exists between the two variables under investigation relationship exist. According to Argosy (2014) the use of correlation coefficient process is to be able to make predictions based on existing positive and negative relations. However, if we know the value of one variable, that we should be able to predict the value of the other variable. It’s also important thing to remember...

...same data on my term paper. I will be comparing runway incursions that took place between 2011 and 2012. The data from this group will be independent of each other. The F-Test can also be conducted with data that is unpaired. Data Collection: Techniques in data collection can be from the entire population, or it can be from sample data, which can be random or selected from the population. In the runway incursion F-test the data will be collected from the entire population. Review: The data that was collected for this test was taken from the FAA website, which gives runway incursion totals for each quarter. The given data is from the population. I have chosen the F-test because this will give us variance. Critique: There were a few other tests that could have been conducted, but the F-test was the one that would give me the best results. The T-Test would have been an option for me if I were comparing variance for a single sample. A second option would have been the Chi-test for independence, the problem with this test was I wasn’t testing for independence. I was testing for variance. The F-test was the best fit because I had more than one sample set that was independent from each other. Interpretation: This is where we analyze our hypothesis. In statistical test you have a null hypothesis and a hypothesis. In this case my null hypothesis was there no significant variability differences between runway incursions in 2011 and 2012. The hypothesis was that there were...
