In a study of hypertension and optimal treatment conducted by the National Heart Institute, 10,000 patients had a mean systolic blood
pressure, = mm Hg and standard deviation, = mm Hg.
Assume the systolic blood pressure is normally distributed.
a) What is the probability of patients with a systolic blood
pressure of more than 180 mm Hg?
b) How many patients will have a systolic BP of more than 180
mm Hg?
c) What is the probability of patients with a systolic blood
pressure between 145 and 160 mmHg?
d) If 60 random samples each of size 30 are drawn from this
population, determine:
i. the sampling distribution of the mean systolic blood
pressure.
ii. the probability that the of mean systolic blood pressure
will be less than 165 mmHg.

the answer is a.

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
