Problem 10.28

The commercialism of the U.S. space program has been a topic of great interest since Dennis Tito paid $20 million to ride along with the Russian cosmonauts on the space shuttle.8 In a survey of 500 men and 500 women, 20% of the men and 26% of the women responded that space should remain commercial free. a Does statistically significant evidence exist to suggest that there is a difference in the population proportions of men and women who think that space should remain commercial free? Use a .05 level test. b Why is a statistically significant difference in these population proportions of practical importance to advertisers?
