1. Systolic Blood Pressure Assume that the mean systolic blood pressure of normal adults is

120millimeters of mercury (mmHg ) and the standard deviation is 5.6 . Assume the variable is normally distributed. Round the answers to at least 4 decimal places and intermediate z -value calculations to 2 decimal places.

2. Ages of Proofreaders At a large publishing company, the mean age of proofreaders is 36.2 years and the standard deviation is 3.7 years. Assume the variable is normally distributed. Round intermediate years. Assume the variable is normally distributed. Round intermediate z -value calculations to two decimal places and the final answers to at least four decimal places.

If a proofreader from the company is randomly selected, find the probability that his or her age will be between 36 and 37.5 years
