The National Institute on Alcohol Abuse and Alcoholism has indicated that 52 percent of 18-22 year old college students have had an alcoholic drink in the past month. Suppose Western Carolina University's Division of Student Affairs takes a sample of 170 students between the ages of 18 and 22. NOTE: For the following problems, you should use a standard deviation, s, rounded to THREE decimal places. A. What is the probability that the proportion of WCU students from the sample, p, who drank in the past month is greater than 0.63? Probability = B. What is the probability that the proportion of WCU students from the sample, p, who drank in the past month is between 0.43 and 0.76? Probability= C. 20 percent of the sample proportions, p, are less than this value, C. C =
