Two different questionnaire formats designed to measure alcohol consumption - one encompassing all types of food in the diet and the other specifically targeting alcohol use - were compared for males and females between 50 and 65 years of age living in a particular community [270]. For each of the alcoholic beverages beer, liquor, red wine, and white wine, each subject was classified as either a nondrinker (never or less than one drink per month) or a drinker (one or more drinks per month) according to each of the questionnaires. The relevant information pertaining to beer consumption is saved in the dataset alcohol. Categories for the generic questionnaire are saved under the name generic_quest, and those for the questionnaire targeting alcohol use are saved under alcohol_quest.

(a) Test the null hypothesis that there is no association between drinking status and type of questionnaire.
