In an article in the Journal of Advertising, Weinberger and Spotts compare the use of humor in television ads in the United States and the United Kingdom. They found that a substantially greater percentage of U.K. ads use humor.
(a) Suppose that a random sample of 387 television ads in the United Kingdom reveals that 130 of these ads use humor. Find a point estimate of and a 95 percent confidence interval for the proportion of all U.K. television ads that use humor. (Round your answers to 3 decimal places.)

A theater is presenting a program on drinking and driving for students and their parents or other responsible adults. The proceeds will be donated to a local alcohol information center. Admission is
$ 2.00$2.00
for adults and
$ 1.00$1.00
for students. However, this situation has two constraints: The theater can hold no more than
150150
people and for every two adults, there must be at least one student. How many adults and students should attend to raise the maximum amount of money?

Problem 2: The average Saturday attendance at a movie theater is 974 people with a standard deviation of 54 people. A random sample of 39 Saturdays is selected
Part A: What is the probability that a sample mean will be either less than 954 people or greater than 970 people?
Part B: There is a 97% chance that a sample mean will be above what attendance level?
Part C: What is the probability that more than 1000 people will attend the theater this Saturday?
