5. Solve the following problem using a Venn diagram: Consider the following data among 110 students in the college dormitory: 30 students are on a list A (taking Accounting); 35 students are on a list B (taking Biology); and 20 students are on both lists.

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. How many males are in the sample? 310 b. How many females are in the sample? 190 c. How many males in the sample eat breakfast? d. How many females in the sample do not eat breakfast? e. What is the probability of selecting a female who doesn't eat breakfast? Round your answer to two decimal places. II

A researcher is interested in the affects that a person’s avatar (i.e. visual representation of oneself) has on the number of profile views on Facebook.com.  The average number of individual personal profile views is known to be 230 views per day (excluding bands, artists, etc.).  The researcher creates 36 fictitious profiles that contain roughly the same information but the picture (avatar) is an animated .gif of a smiling face (36 faces randomly selected from a compilation of faces judged to be of average attractiveness).  The results showed that of the 36 profiles the average number of views was 250 with a standard deviation of 60.  Test the hypothesis that the average number of views for a smiling face gif is significantly different than the usual number of personal profile views.

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.)
