Diastolic blood pressure is a measure of the pressure when arteries rest between heartbeats. Suppose diastolic blood pressure levels in women are normally distributed with a mean of 70.2 mm Hg and a standard deviation of 10.8 mm Hg. Complete parts (a) and (b) below a. A diastolic blood pressure level above 90 mm Hg is considered to be hypertension. What percentage of women have hypertension? 3.34 % (Round to two decimal places as needed.) b. If we randomly collect samples of women with 25 in each sample, what percentage of those samples have a mean above 90 mm Hg? % (Round to two decimal places as needed.)
