...testing a research hypothesis, comparing the means of two or more groups, and calculating the correlation between two variables. The following paper will go in to more depth on what was discussed and what we learned as a team as well as individuals. The team also was able to go over the Mystat lab that we were assigned in the individual assignment. In step one a team would state a null hypothesis as well as an alternate hypothesis. The null hypothesis is used only for testing. We either reject or fail to reject the null hypothesis. The alternate hypothesis is accepted if sample data provide enough evidence that the null hypothesis is false. No matter what the problem looks like the null hypothesis will always contain the equal sign. This is true because since the null hypothesis is being tested there is a need for a specific value to be seen in the calculations. When comparing the means of two or more groups the team must state the null hypothesis. Random samples of each population must be chosen to show the formula in a working status. To get a more accurate sample a higher number of the populations should be used. An independent sample T-test is used to compare the means of two or more groups. Pooled variance can be used if the variances of the two populations being tested are constant. The correlation between two variables describes the likelihood that a change in one variable will cause a proportional change in the other variable. A high correlation between two...

...Solving Proportions To estimate the size of the bear population on Keweenaw Peninsula, conservationists Captured, tagged, and released 50 bears. One year later, a random sample of 100 bears included only 2 tagged bears. The question I am asked is what do conservationist’s estimate of the size of the bear population? You will notice while reading question #56 on page 437, we are to assume that the ratio of originally tagged bears to the whole population is equal to the ratio of recaptured tagged bears to the size of the sample. The ratio of originally tagged bears to the whole population is 50X The ration of recaptured tagged bears to the sample size is 2100 50X=2100 This is the proportion set up and ready to solve. I will cross multiply setting the extremes equal to the means. 10050=2x 100and 50 are the extremes, while X and 2 are the means. 50002=2x2 Divide both sides by 2 X = 2500 The bear population on the Keweenaw Peninsula is around 2500 bears. The second problem for assignment one week one I am asked to solve the below equation for y. The first thing I notice is that a single fraction (ratio) on both sides of the equal sign so basically it is a proportion which can be solved by cross multiplying the extremes and the means. y-1x+3=-34 Is the equation I am asked to solve. 3y-1=-3x-4 The result of the cross multiplying. 3y-3=-3x+12 Distribute 3 on the left side and -3 on the right. 3y-3+3=-3x+12+3 Subtract 3 from both sides. 3y=-3x+15 3y3=-3x3+153...

...Diagnostic Algebra Assessment Definitions Categories Equality Symbol Misconception Graphing Misconception Definition Concept of a Variable Misconception Equality Symbol Misconception As algebra teachers, we all know how frustrating it can be to teach a particular concept and to have a percentage of our students not get it. We try different approaches and activities but to no avail. These students just do not seem to grasp the concept. Often, we blame the students for not trying hard enough. Worse yet, others blame us for not teaching students well enough. Students often learn the equality symbol misconception when they begin learning mathematics. Rather than understanding that the equal sign indicates equivalence between the expressions on the left side and the right side of an equation, students interpret the equal sign as meaning “do something” or the sign before the answer. This problem is exacerbated by many adults solving problems in the following way: 5 × 4 + 3 = ? 5 × 4 = 20 + 3 = 23 Students may also have difficulty understanding statements like 7 = 3 + 4 or 5 = 5, since these do not involve a problem on the left and an answer on the right. Falkner presented the following problem to 6th grade classes: 8 + 4 = [] + 5 All 145 students gave the answer of 12 or 17. It can be assumed that students got 12 since 8 + 4 = 12. The 17 may be from those who continued the problem: 12 + 5 = 17. Students with this misconception may also have difficulty with the idea that adding...

...Team B Calorie Count Tool PRG/211 May 5, 2014 Team B Calorie Count Tool PROBLEM STATEMENT Team B was asked to develop a program which would calculate the user’s daily intake of calories and measure those calories against the overall calories expended. The core purpose of this program will do two primary functions. First, it will record the user intake of calories as acquired through meals throughout the day. Second, the user will record caloric output associated with physical activity. This information will be calculated together to determine the caloric surplus or deficit for the user. In order for the program to execute accurately, and provide customized results, the user will be required to input personal data to include gender, age, weight, and height. This additional information is essential to determine the user’s default caloric burn rate, otherwise known as the basal metabolic rate (BMR). The BMR and the calories burned as a result of physical activity will be calculated against the intake of calories to determine the overall success for the user. As the program is executed it must: * Record user name, age, height, weight to enable more accurate calculations * Record the users specific caloric values entered for each meal * Record the user activity and caloric burn values for that activity * Calculate the basal metabolic rate (BMR) for the individual * Subtotal the total caloric values for the day * Combine the physical activity and...

The operand (the value on which the operator operates ) of the unary operator must have arithmetic or pointer type and the result is the value of the argument. Example:- If a=5 then +a means 5 If a=0 then +a means 0. If a=-4 then +a means -4. Ternary operator:- It precedes an operand. The operand of the unary operator must have arithmetic type and the result is the negation of the operand’s value. Example:- If a=5 then –a means -5 If a=0 then –a means 0 If a=-4 then –a means 4. (b) Assignment and equalto operator Assignment operator:- Equal to operator: An assignment operator assigns value In this we put the To a variable. value as it is.

...Selection statements Selection is used to select which statements are to be performed next based on a condition being true or false. Relational expressions In the solution of many problems, different actions must be taken depending on the value of the data. The if statement in C I used to implement such s decision structure in its simplest form – that of selecting a statement to be executed only if a condition is satisfied. Syntax: if(condtion) statement executed if condition is true When an executing program encounters the if statement, the condition is evaluated to determine its numerical value, which is then interpreted as either true or false. If the condition evaluates to any non-0 value (positive or negative), the condition is considered as a “true” condition and the statement following the if is executed; otherwise this statement is not executed. Relational Operators In C Relational operator | Meaning | Example | < | Less than | age < 30 | > | Greater than | height > 6.2 | <= | Less than or equal to | taxable <= 200000 | >= | Greater than or equal to | temp >= 98.6 | == | Equal to | grade == 100 | != | Not equal to | number !=250 | In creating relational expressions, the relational operators must be typed exactly as given in the above table. Thus, although the following relational expressions are all valid: age > 40 length <= 50 temp >= 98.6 3 < 4 flag == done day != 5 The following are invalid: length =< 50 ...

...Sarah Waters (Use your name) Mr. Ervin (Please use this designation for my name.) AASC 3301.02 (Use your course and section designation) 10 February 2009 (Use due date) Sartre’s Nausea (Center title) Published in April of 1938, Nausea was Jean-Paul Sartre’s first novel. What began as a twenty-six year old scholar’s “pamphlet on contingency” (Duncan 91) remains a work of profound literary and philosophical influence. Nausea is set in a fictional Bouville, France. Walters indicates, “Bouville is Sartre’s fictional version of the western French port Le Havre” (para. 1). In early January, 1932, Antoine Roquentin begins his diary as a means to think through changes in his perception of the world. Discrepancies make it difficult to establish specific dates. Roquentin’s initial dated entry is “Monday, 29 January, 1932” (4). However, 29 January, 1932, was a Friday. Additionally, the third through sixth entries include two Thursdays and Fridays. If those are accurately labeled, they are separated by a week. Given that, the record must cover a five-week period. However, the time span will not accommodate five weeks. Therefore, the initial two Thursdays and Fridays are either not separated by a week or are mislabeled. Dating the fifth entry, “Thursday, 11.30” (27-30) 4 February, 1932, brings the remaining entries into a coherent sequence. Assuming that the date for the initial entry is 29 January, 1932, and that Roquentin met Anny on Saturday, 20 February, the diary begins on...

...Law Written Assignment 3 Case Study 1 Parks, a 7-foot, 265-pound center for the San Diego Slick, objected when his contract was assigned from the ABC Corporation to the XYZ Corporation, the team’s new owner. The change of owners did not cause a change in the composition of the team although a new coach was hired. Parks’s compensation and his responsibilities remained the same. Was this contract assignable? Facts of the Case: 1) Parks contract was assigned from the ABC Corporation to XYZ Corporation. 2) Parks compensation and his responsibilities remained the same. Issues: 1) The reason why we are in court today is to identify if Park’s contract was assignable. Rules of the Law: 1) Personal Service Contract – The parties agree that a personal service contract may be assigned. This allows the trade of an athlete from one team to another team. 2) Notice of Assignment – Assignee is under a duty to notify the obligor that the assignment has been made and performance must be rendered to the assignee. 3) Anti-Assignment Clause – Prohibits the assignment of rights under the contract. 4) Approval Clause – requires that the obligor approves any assignment of contract. Analysis & Conclusion: Since we do not have all the facts we can assume the following: 1) Parks contract did include the Personal service contract. 2) Notice of assignment was made by XYZ Corporation. 3) Parks contract did NOT include Anti-Assignment Clause. ...
