1. In the NHANES I survey the distribution of the systolic blood pressure (SBP) of 25-35 year-olds is approximately Normally distributed. For men the mean SBP was 125 with standard deviation (SD) of 14 mm Hg. The mean SBP for women was 118 mm Hg with SD 15. According to new guidelines put out by the American Heart Association in November 2017, hypertension is now indicated for someone with SBP > 130 mm Hg.
What is the approximate median SBP for the men in this sample?
A. Approximately what percentage of women have SBP > 133 mm Hg?
B. Approximately what percentage of menhave SBP < 97 mm Hg?
C. What would be the sex-specific Z scores for men and women in this age group which would correspond to an indication for hypertension (SBP = 130 mm Hg)?
D. Use a Normal distribution calculator (https://stattrek.com/online-calculator/normal.aspxis one) to estimate what percentages of women and men in this age group would be classified as hypertensive.
