Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

- Explain the differences between Gaussian elimination and Gauss-Jordan elimination.When looking at the data for graduate school admissions between men and women, it is shown that about 45% of men are admitted but only 38% of women. However, when the data is broken down by school it turns out that, within each school, the women are admitted at higher rates than the men. This could happen because I. The women apply in higher numbers to schools with lower acceptance rates. II. The women apply in higher numbers to schools with higher acceptance rates III. The men apply in higher numbers to schools with lower acceptance rates IV. The men apply in higher numbers to schools with higher acceptance ratesA researcher wishes to compare the effectiveness of group therapy to placebo “antidepressants” (i.e., sugar pills that people think are antidepressants) on negative feelings associated with break-ups. He finds 22 people who went through a break-up in the last 2 weeks. He places half of them in a therapy group that meets every day for 2 weeks. He gives the other half the sugar “antidepressant” (placebo) every day for the same time. Unfortunately, he soon discovers that two participants from the Group Therapy session are now dating each other. Because he is worried that their data will not be representative of the effects of group therapy, he decides to remove their data from that sample. So now, the Group Therapy sample only includes 9 participants. The researcher thought that the effects of Group Therapy might be different from those of Placebo antidepressants, but he is not sure how. At the end of the 2 weeks of treatment, he asks all participants to rate their negative feelings on a…

They conducted a poll of its subscribersits subscribers with a response rate of 2424%. On the basis of the results, the magazinemagazine predicted that Candidate A would win with 57% of the popular vote. However, Candidate B won the election with about 62% of the popular vote. At the time of this poll, most subscribers to the magazinesubscribers to the magazine belonged to the party of Candidate A. Name two biases that led to this incorrect prediction.Choose the correct answer below. A.Nonresponse bias: The low response rate caused bias.Response bias: The way the poll was administered showed bias. B.Sampling bias: Using an incorrect frame led to undercoverage.Nonresponse bias: The low response rate caused bias.

The test is 98%accurate, which means that, if you have the disease, 98% of the times the testwill come out positive and 2% negative. Also, if you do not have the disease, the test will come out negative 96% of the time and positive 4% of the time. You take the test and it comes out positive. What is the probability that you have the disease?
- In a top business school, 60% of its students are female, and 40% are male. All of them have totake a core module, Business Analytics. Although there are quite a number of students who like themodule, there are also quite a number who dislike it. The remaining students are indifferent to it.A study found that 40% of the female students dislike the module. Only 25% of male students dislikeit. Moreover, only 10% of students are indifferent to it. Interestingly, equal numbers of male andfemale students are indifferent to it, among all students. Given that a student who like Businessanalytics, what is the probability that this student is a male student?A professor has been teaching an undergraduate course for the last 15 years and has noticed that in the fall term there are more failures than in the same course offered in the winter term. The professor is wondering if this may be due to students being less prepared for the subject matter in the fall than in the winter because more students are taking the prerequisite simultaneously. Before drawing any conclusions though, the professor goes back over all the grades in all classes she taught in the last 15 years and counts the number of students that passed or failed. She then also records who had and had not completed the prerequisite first (see the table attached for data). On the basis of the last 15 years of data, should the 3 professor conclude that there is a difference in pass and failure rates depending on whether the prerequisite was done or not? Use the alpha of 0.05 and carry out all the steps of hypothesis testing to answer the hypothesis.A company produces three different products; x,y, and z. For the production of 1 unit of product x, 1 unit of A and 1 unit of B are used as input. 1 unit of A and 2 units of B are used to produce 1 unit of product y. To produce 1 unit of product z, only 1 unit of A is used. The company holds 40 units of A and 20 units of B periodically in total. By the way, the company can not produce product y more than the twice of product z. On the other hand, the sale price of 1 unit of product x is 10 TL, product y is 15 TL and product z is 12 TL. Furthermore, the cost of 1 unit of product x is 8 TL, product y is 9 TL and product z is 7 TL. Solve the above problem by using Simplex Method. Linear Programming

The students are given three chances to pass the exam; 55% pass it on their first attempt, 64% of those that take it a second time pass it then, and 43% of those that take it a third time pass it then. (Assume that all students who do not pass the first or second time elect to take the test again.)What percentage of the students are not allowed to graduate because of their performance on the exam? (Round your answer to one decimal place.)
