A television station wishes to study the relationship between viewership of its 11 p.m. news program and viewer age (18 years or less, 19 to 35, 36 to 54, 55 or older). A sample of 250 television viewers in each age group is randomly selected, and the number who watch the station’s 11 p.m. news is found for each sample. The results are given in the table below.

If these proportions are equal, then whether a viewer watches the station’s 11 p.m. news is independent of the viewer’s age group. Therefore, we can test the null hypothesis H0 that p1, p2, p3, and p4 are equal by carrying out a chi-square test for independence. Perform this test by setting α = .05.

National polls from October 2016 showed that preferences for the 2016 presidential election differed along gender lines. Poll results showed that a greater percentage of likely female voters supported Clinton/Kaine, while a greater percentage of likely male voters supported Trump/Pence. A summary of poll results are shown in the table below. Men Women Clinton/Kaine 0.44 0.49 Trump/Pence 0.47 0.43 Based on this data, answer the following questions. Assume each person selected is independent from one another. Round your answers to 3 decimal places.(a) If 10 women across the US are randomly selected, find the probability that 9 or more support Clinton/Kaine. (b) If 20 men across the US are randomly selected, find the probability that 16 or less support Trump/Pence. (c) If 260 women across the US are randomly selected, how many would you expect to support Clinton/Kaine? (d) If 240 men across the US are randomly selected, how many would you expect to support Trump/Pence?
