a. Conduct the appropriate hypothesis test to determine whether there is any evidence to suggest that the true proportion of 18-29-year-olds who believe movies are getting better is greater than the proportion of 30-49-yearolds. Use a = 0.001.
b. Find the p value associated with the hypothesis test in part (a).
