Use the empirical rule to solve the problem. The systolic blood pressure of 18 yr. old women is normally distributed with a mean of 120 mmHg (millimeters of Mercury) and a standard deviation of 14 mmHg. What is the percentage of 18 yr. old women that have a systolic blood pressure between 92 mmHg and 162 mmHg.

Homework Answers

Answer #1

Solution:- The percentage of 18 yr. old women that have a systolic blood pressure between 92 mmHg and 162 mmHg is 97.6%.

x1 = 92

x2 = 162

By applying normal distruibution:-

z1 = - 2.0

z2 = 3.0

P( - 2.0 < z < 3.0) = 0.977 - 0.001

P( - 2.0 < z < 3.0) = 0.976
