Diastolic blood pressure. In a study of 500 men, diastolic blood pressure was found to be approximately normally distributed, with a mean of 82 millimeters (mm) of mercury and standard deviation of 10 millimeters. a. Use the 68–95–99.7% rule to determine what percentage of the test group had a diastolic pressure between 72 millimeters and 92 millimeters of mercury. b. Use your answer to part a to determine how many men in the test group had a diastolic pressure between 72 millimeters and 92 millimeters of mercury.
