Textbook Question

Chapter 10.3, Problem 7P

This question was asked by a research group on behalf of The National Institute (Reference: Painting by Numbers. J. Wypijewski, University of California Press). Of a random sample of n 1 = 220 women, r 1 = 59 responded yes. Another random sample of n 2 = 175 men showed that r 2 = 56 responded yes. Does this information indicate a difference (either way) between the population proportion of women and the population proportion of men who favor spending more federal tax dollars on the arts? Use α = 0.05 .
