-The systolic blood pressure of a group of 18-year-old women is normally distributed with a mean of 120 mmHg and a standard deviation of 12 mmHg. What percentage of 18-year-old women in this group have a systolic blood pressure between 108 mmHg and 132 mmHg?

The 68-95-99.7 rule, also known as the empirical rule, states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean. In this case, one standard deviation from the mean (120 mmHg) is 108 mmHg to 132 mmHg (120 - 12 to 120 + 12), so 68% of the group's systolic blood pressure falls within this range.
