What is the percentage of 18 yr. old women that have a systolic blood pressure between 92 mmHg and 162 mmHg.

Z = (score-mean)/SD
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability between the two Z scores. Multiply by 100.
