Watch your cholesterol: The mean serum cholesterol level for U.S. adults was 198, with a standard deviation of 39.3 (the units are milligrams per deciliter). A simple random sample of 106 adults is chosen. Use the TI-84 calculator. Round the answers to four decimal places. Part 1 of 3 What is the probability that the sample mean cholesterol level is greater than 205? The probability that the sample mean cholesterol level is greater than 205 is Part 2 of 3 What is the probability that the sample mean cholesterol level is between 186 and 192? The probability that the sample mean cholesterol level is between 186 and 192 is Part 3 of 3 Would it be unusual for the sample mean to be less than 194? Х It (Choose one) be unusual for the sample mean to be less than 194, since the probability is Х ⑤ would not would
