- A study of the career plans of young women and men sent questionnaires to all 722 members of the senior class in the College of Business Administration at a given University. One question asked which major within the business program the student had chosen. Here are the data from the students who responded Major Accounting Administration Economics Finance Female 68 91 Male 56 40 6 59 61 Does the data suggest that there is a relationahip between the gender of students and their choice of major? At 0.05 level of significance, what is the conclusion to the test? Select the correct response: There is sufficient evidence to conclude that students find Economics very hard. There is insufficient evidence to conclude that the choice of major and the gender of the student are not independent of each other. There is insufficient evidence to conclude that more females prefer Administration than males. There is sufficient evidence to conclude that the choice of major and the gender of the student…Please answer all thoroughly and clearly Grade 12 Data ManagementThe owner of a chain of mini-markets wants to compare the sales performance of two of her stores, Store 1 and Store 2. Sales can vary considerably depending on the day of the week and the season of the year, so she decides to eliminate such effects by making sure to record each store's sales on the same 12 days, chosen at random.

Suppose a computer manufacturer receives circuit boards in batches of five. Two boards are selected from each batch of inspection. We can represent possible outcomes of the selection process by pairs. For example, the pair (1,2) represents the selection of boards 1 and 2 for inspection. (a) List the ten different possible outcomes. (b) Suppose that boards 1 and 2 are the only defective boards in a batch. Two boards are to be chosen at random. Define X to be the number of defective boards observed among those inspected. Find the probability distribution (pmf) of X. (c) Let F denote the cdf of X. Determine F(0), F(1) and F(2); then obtain F(x) for all other x.A survey of 500 people were asked this same question and the results were recorded in a tree diagram in terms of percentages where M = male, F = female, E = eats breakfast, D = doesn't eat breakfast 58% 62% M. 42%= 40% %3D 38% F 60% a.

- Otitis media, or middle ear infection, is initially treated with an antibiotic. Researchers have compared two antibiotics, A and B, for their cost effectiveness. A is inexpensive, safe, and effective. B is also safe. However, it is considerably more expensive and it is generally more effective. Use the tree diagram to the right (where the costs are estimated as the total cost of medication, office visit, ear check, and hours of lost work) to answer the following. a. Find the expected cost of using each antibiotic to treat a middle ear infection. b. To minimize the total expected cost, which antibiotic should be chosen? a. The expected cost of using antibiotic A is S (Round to the nearest cent as needed.)
