Question: = 11 = 12 = 13 = 16 = 17 = 18 19 = 10 = 14 = 15 Watch your cholesterol: The mean serum

= 11 = 12 = 13 = 16 = 17 = 18 19 = 10 = 14 = 15 Watch your cholesterol: The mean serum cholesterol level for U.S. adults was 200, with a standard deviation of 40.6 (the units are milligrams per deciliter). A simple random sample of 106 adults is chosen. Use the TI-84 Plus calculator. Round the answers to at least four decimal places. Part: 0 / 3 Part 1 of 3 (a) What is the probability that the sample mean cholesterol level is greater than 210? The probability that the sample mean cholesterol level is greater than 210 is 0.0056 5 X Part: 1 / 3 Part 2 of 3 (b) What is the probability that the sample mean cholesterol level is between 189 and 197? The probability that the sample mean cholesterol level is between 189 and 197 is 0.2204 5 X Part: 2 / 3 Part 3 of 3 (c) Using a cutoff of 0.05, would it be unusual for the sample mean to be less than 196? It Select be unusual for the sample mean to be less than 196, since the probability is X Continue
