We now consider a random sample of fifty 18-20 year olds. (a) How many people would you expect to have consumed alcoholic beverages? (round to one decimal place) What is the standard deviation? (round to two decimal places) (b) Would you be surprised if there were 45 or more people who have consumed alcoholic beverages? O Yes, 45 is more than two standard deviations above the expected value (mean) No, it is just as likely as any other outcome No, 45 or more accounts for six different events -- this wouldn't be surprising O Yes, 45 out of 50 is 90% (c) What is the probability that 45 or more people in this sample have consumed alcoholic beverages?
