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.
