Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters, for a sample of 8 adults. The following table presents the results. The 99% confidence interval is

B) We are 87% confident that the true average of students who do aerobics is between 28.8% and 39.9%. C) We are 95% confident that the true proportion of students who do aerobics is between 28.8% and 39.9%. D) We are 87% confident that the true proportion of students who do aerobics is between 27.3% and 41.7%.
