Transcribed Image Text:

The mean total cholesterol for a population of men between the ages of 20 and 29 is 180 micrograms per deciliter with a standard deviation of 36.7. A healthy total cholesterol level is less than 200, 200-240 is borderline, and above 240 is dangerous. Assume the distribution is approximately Normal. Complete parts a through d. a. For a randomly selected man from this group, what is the probability that his total cholesterol level is 200 or more? The probability is | that his total cholesterol level is 200 or more. b. For a randomly selected man from this group, what is the probability that his total cholesterol level is 240 or more? The probability is | that his total cholesterol level is 240 or more. c. If two randomly selected men are chosen from this group, what is the probability that both will have a total cholesterol level of 200 or more? Assume independence. The probability is that both men will have a total cholesterol level of 200 or more. d. If 750 randomly selected men are chosen from this group, how many (the count, not the percentage) would you expect to have a total cholesterol level of 200 or more? You would expect men to have a total cholesterol level of 200 or more.
