Please only answer of 5.73
### Blood Pressure Analysis for 50-Year-Old Women In this analysis, we consider the systolic blood pressure (SBP) for a 50-year-old woman, which averages 125 mm Hg with a standard deviation of 15 mm Hg. SBP is assumed to be normally distributed. #### Problem 5.71 *What proportion of 50-year-old women is hypertensive if hypertension is defined as SBP ≥ 140 mm Hg?* #### Clinical Trial Insight Previous trials estimate a 3 mm Hg reduction in mean SBP for every 10 lbs. of weight loss. #### Problem 5.72 *Suppose an average woman did not gain any weight from age 18 to 50. What average SBP for 50-year-old women would be expected under these assumptions?* #### Problem 5.73 *If the standard deviation of SBP remains 15 mm Hg and the distribution stays normal, what would be the expected proportion of hypertensive women under the assumption in Problem 5.72?* #### Problem 5.74 *What percentage of hypertension at age 50 is attributable to weight gain from age 18 to 50?* This analysis examines how maintaining weight from age 18 to 50 affects SBP and the prevalence of hypertension.

**Cardiovascular Disease** Obesity is an important determinant of cardiovascular disease because it directly affects several established cardiovascular risk factors, including hypertension and diabetes. It is estimated that the average weight for an 18-year-old woman is 123 lbs. and increases to 142 lbs. at 50 years.

Step 1

Given Information:

The average weight of an 18-year-old woman is 123 lbs and increases to 142 lbs at 50 years of age.

Mean μ=125 mm Hg

Standard deviation σ=15 mm Hg

For every 10 lbs of weight loss, there is, on average, a corresponding reduction in mean SBP of 3 mm Hg.
