Question

A normal blood pressure for a man in his late forties is

130/82 mm Hg. Why are there two number?

Answer #1

Assume that the mean systolic blood pressure of normal adults is
120 millimeters of mercury (mm Hg) and the standard deviation is
5.6. Assume that the variable is normally distributed. If an
individual is selected, find the probability that the individual’s
systolic blood pressure will be between 118.4 and 121.9 mm Hg.

A person is considered “prehypertensive” if his systolic blood
pressure is between 120 and 130 mm Hg.
Find the probability that the blood pressure of a randomly
selected person is prehypertensive.

Listed below are systolic blood pressure measurements (mm Hg)
taken from the right and left arms of the same woman. Assume that
the paired sample data is a simple random sample and that the
differences have a distribution that is approximately normal. Use a
0.05 significance level to test for a difference between the
measurements from the two arms. What can be concluded? Right arm

Assume that the mean systolic blood pressure of normal adults is
120 millimeters of mercury (mm Hg) and the population standard
deviation is 5.6. Assume the variable is normally distributed. If a
sample of 30 adults is randomly selected, find the probability that
the sample mean will be between 120-mm and 121.8-mm Hg.
