We find that students are often confused about which variable is independent and which is dependent in a regression model. For example, in Triple A’s problem, clarify which variable is X and which is Y. Emphasize that the dependent variable (Y ) is what we are trying to predict based on the value of the independent (X) variable. Use examples such as the time required to drive to a store and the distance traveled, the totals number of units sold and the selling price of a product, and the cost of a computer and the processor speed. Teaching Suggestion 4.2: Statistical Correlation Does Not Always Mean Causality. Students should understand that a high R2 doesn’t always mean one variable will be a good predictor of the other. Explain that skirt lengths and stock market prices may be correlated, but raising one doesn’t necessarily mean the other will go up or down. An interesting study indicated that, over a 10-year period, the salaries of college professors were highly correlated to the dollar sales volume of alcoholic beverages (both were actually correlated with inflation). Teaching Suggestion 4.3: Give students a set of data and have them plot the data and manually draw a line through the data. A discussion of which line is “best” can help them appreciate...

...improvement and future success of this company moving into the public market. In order to properly perform an assessment of the LBJ Company, there first had to be some set of standards or regulations that outline the internal controls and proper procedures for companies and businesses to adhere to for financial reporting. As it turns out internal control is a key component of Foreign Corrupt Practices Act(FCPA) of 1977 and the Sarbanes-Oxley Act(SOX) of 2002 which required companies to follow this set of internal controls. This list of internal controls is as follows: 1). Conduct its business in an orderly and efficient manner, 2). Safeguard its assets and resources, 3). Deter and defect errors, theft, and fraud, 4). Ensure accuracy and completeness of accounting data, 5). Produce reliable and timely financial and management information, 6). Ensure adherence to its policies and plans.(O’Malley) From this point on all senior management officials will be held responsible for enforcing and ensuring that their company follows these regulations and...

...such as someone’s vacation hours and stocking merchandise for the store, those tasks should be delegated out to the assistant manager and to the store clerks. Being a supervisor means being in a role of leadership, logic, common sense, and decision making for yourself, the employees, and for the company. The “in Basket” debate and discussion gives us and our fellow classmates the opportunity to see if we can successfully delegate out certain tasks as a supervisor at a fictitious company. The discussion between me and fellow classmates was a great one and it appeared as though everyone agreed on everything accept for different incidents. The only two incidents where I came across disagreement were in regards to task number 3, and task number 4. These are the examples in which I will be using in this paper as far as disagreeing is concerned. Task number 3 is in regards to the mall hours changing for an upcoming holiday and that there is a request for store plans. In my own opinion and the opinion of all of my fellow classmates accept for one that I could find agreed that this task needed to be done by the Supervisor. The disagreeing student felt that it should be delegated to the Assistant Manager. This task should be done by the supervisor because it is not only a very important one...

...Corridors of Transition between 12 Angry Men and 12 “I have always found that mercy bears richer fruits than strict justice”. Abraham Lincoln “The virtue of justice consists in moderation, as regulated by wisdom”. Aristotle ”Nobody gets justice. People only get good luck or bad luck”. Orson Welles Justice = mid-12c., "the exercise of authority in vindication of right by assigning reward or punishment;" also "quality of being fair and just," from Old French justice "justice, legal rights, jurisdiction" (11c.), from Latin iustitia "righteousness, equity," from iustus "upright, just" . The Old French word had widespread senses, including "uprightness, equity, vindication of right, court of justice, judge." The word began to be used in English c.1200 as a title for a judicial officer. Meaning "right order, equity" is late 14c. Justice of the peace first attested early 14c. In the Mercian hymns, Latin iustitia is glossed by Old English rehtwisnisse. To do justice to (someone or something) "render fully and fairly showing due appreciation" is from 1670s. This word, with such a strong connotation, influenced and formed the basis of many philosophical...

...CHAPTER I INTRODUCTION Not all people are given the chance to have a quality education especially in the Philippines because it is now complicated. That’s why having the chance to study and choosing the course should not be compared to some thing like for an example buying a dress for a special occasion and when realization comes into your mind that you don’t want it, you’ll return it or maybe get your money back. No, this isn’t right, because in college life, you have to treat every second as an important detail of your life. You should not waste every moment in it. So choosing the course which you think fits your capabilities is very important. Studying a specific course in college is not only about paying the fees rather the most important things here are the time and effort spent. Money, time and effort are the most precious things in one’s life and once it is used or spent, it’s hard to gain again or worst you may never have it at all. So the time these are wasted for nothing, for sure the blame for this mistake will be felt truly. When looking at the profile of those students who are working and at the same time is studying, you would notice that they never dare wasting their time. For them, every second counts. Make an observation and you will find out that almost all of the working students are working too hard to finish their studies. For them, wasting their effort, time and money is such a big mistake. OBJECTIVES OF THE STUDY The objective of studying...

...1. How did Turner get himself into this particular predicament? Solution: The following reasons form the root cause of Turner being so indecisive about his position at MLI towards the end of the case: Firstly, Jamie Turner earlier worked at Wolf River, where departments such as control, budgeting, planning and similar tasks were well supported. When he was allowed autonomy and was all on his own, he could not get enough time to prepare himself for all the challenges that were posed for his position and he ended making hasty decisions based on his prior experience. Secondly, his differences with Cardullo regarding their views on the cash flow problem, pricing halogen bulbs below the break-even point with reduced margins, and their other arguments left Turner in distaste and anger. Turner’s strategy of reducing production cost and lesser margins did not go well with Cardullo who wanted higher margins for his products. Moreover, Turner was initially indecisive about joining MLI given the financial situation of the company and other complexities that a merger had created. Also, he was not really keen to go into industrial marketing. He did not weigh the positives and negatives completely before accepting the offer at MLI and started repenting his decision after just a few months into the company. All these things along with the problem of dealing with Julie Chin, lead to this particular predicament. 2. What did Pat Cardullo and Jamie Turner each initially bring to the situation...

...First, in chapter one I learned that competition is very important in the growth of a company. This is true because it motivates them to create better quality goods or services at a cheaper price or lower rate, with the end goal of attracting more customers. However, in some cases rival companies have been known to take the competition too far by focusing on ruining the other company rather than making their own better. Second, in chapter two I learned that one of the keys to a successful business is that it develops and keeps a good ethical image. For example, the issue of environmental protection has been given increasing importance since the late 20th century. Therefore, governments around the world have begun to pass laws to protect the environment from harmful practices such as improper disposal of medical waste. In response, several companies have created executive positions for a person to help them achieve its goals in an effective and environmentally responsible way. Third, in chapter three I learned that international trade has several barriers, such as economic, ethical, legal, and political barriers. For example, a major legal barrier for the US is all the laws and regulations that have been set in place to govern international trade. Another obstacle companies engaging in international trade must maneuver around is the differences in American laws and any other country's laws concerning currency, taxes, patents, and quota limits. Fourth, in chapter four I learned...

...explain to me that in this game each of us in turn will blindly draw three cards from a partial deck of cards. This deck has had all cards above 9 removed, and for this game’s purposes aces are only equal to 1. Without looking at my cards I am to place them facing out on my forehead so the other players can clearly see the cards. Each of the other players is to do the same. The object of the game is to guess which cards you have on your own head using logic to solve the problem. Players draw question cards that reveal information about player cards, and the first to guess their cards based on the information revealed wins the game. My brother Andy has the cards 1, 5, and 7 showing on his forehead. His wife Belle has 5, 4, and 7. My girlfriend Carol has the cards 2, 4, and 6. Andy is selected to draw the first question card, and it asks if he sees two or more players who’s cards sum to the same value. Andy answers affirmatively. With this information I know that I must have cards that equal either 12 or 16. I know this because Belle’s cards sum to 16 and Carol’s cards sum to 12. Since Andy sees two of us with cars of the same value I am able to confirm that my sum must match either Belle’s or Carol’s. At this point none of us are able to conclude anything else about our cards, so Belle draws the next question card. Belle’s question reads “Of the five odd numbers [1, 3, 5, 7, and 9] how many different odd numbers do you see?” Belle answers that she sees all five the odd numbers. I...
