A marketing research firm wishes to study the relationship between wine consumption and whether a person likes to watch professional tennis on television. One hundred randomly selected people are asked whether they drink wine and whether they watch tennis. The following results are obtained:
a. For each row and column total, calculate the corresponding row or column percentage.
b. For each cell, calculate the corresponding cell, row, and column percentages.
c. Test the hypothesis that whether people drink wine is independent of whether people watch tennis. Set α = .05.
d. Given the results of the chi-square test, does it make sense to advertise wine during a televised tennis match (assuming that the ratings for the tennis match are high enough)? Explain.
