The mean systolic blood pressure of adult males is normally
distributed with a mean of 138 (millimeters of
mercury) and a standard deviation of 9.7. What percent
of adult males have blood pressure between 161.28 and
164.9?
-------------------------
Find the z-value of 161.28 and the z-value of 164.9.
----
If those values are "a" and "b" then:
P(161.28 < x < 164.9) = P(a < z < b) = 0.005422...
