Assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury (mm Hg) and the standard deviation is 5.6. Assume that the variable is normally distributed. If an individual is selected, find the probability that the individual’s systolic blood pressure will be between 118.4 and 121.9 mm Hg.

Assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury (mm Hg) and the population standard deviation is 5.6. Assume the variable is normally distributed. If a sample of 30 adults is randomly selected, find the probability that the sample mean will be between 120-mm and 121.8-mm Hg.

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Using this data, find the 99% confidence interval for the true difference in blood pressure for each patient after taking the new drug. Assume that the blood pressures are normally distributed for the population of patients both before and...
