2. (15 points) A researcher is interested in whether men admit to drunk driving more or less often than women do. She takes a sample of 190 males and 190 females over the age of 21 and asks them to fill out a questionnaire. Early in the questionnaire, respondents are asked whether they have ever consumed alcohol. Respondents saying they have not are eliminated from the samples but are not replaced by someone else. Therefore the final sample sizes for analysis are fewer than 190 each. Use the information below then to test the null hypothesis that there are no differences in the proportion of men and women who say they have driven drunk. Assume alpha is .05 and make sure to include the relevant hypotheses and all steps in your calculations. Interpret your results. Male Female Sample size 180 150 # Driven under the influence 81 48
