What is the answer

Problem 2: Alber's manufactures and distributes two types of beer: light and regular. In an analysis of the market segments for the two beers, the firm's market research group raised the question of whether preferences for the three beers differ among male and female beer drinkers. If beer preference is independent of the gender of the beer drinker, one advertising campaign will be initiated for both of Alber's beers. However, if beer preference depends on the gender of the beer drinker, the firm will tailor its promotions to different target markets.
