Binge drinking among women. The Centers for Disease Control and Prevention finds that 24.2% of women aged 18 to 24 years binge drank. Binge drinking for women is defined as consuming at least 4 alcoholic drinks per episode during the past 30 days. Those who binge drank averaged 6.4 drinks per episode and 3.6 episodes per month. The study took a sample of almost 11,000 women aged 18 to 24 years, so the population proportion of women who binge drank is very close to p 0.24.22 The administration of your college surveys an SRS of 200 female students and finds that 56 binge drink. (a) What is the sample proportion of women at your college who binge drink? (b) If, in fact, the proportion of all women on your campus who binge drink is the same as the national 24%, what is the probability that the proportion in an SRS of 200 students is as large or larger than the result of the administrations sample? (c) A writer for the student paper says that the percent of women who binge brink is higher on your campus than nationally. Write a short letter to the editor explaining why the survey does not support this conclusion.
