☐ A
For women aged 18-24, systolic blood pressures (in mm Hg) are normally distributed with a mean of 114.8
and a standard deviation of 13.1. If 23 women aged 18-24 are randomly selected, find the probability that their
mean systolic blood pressures is between 119 and 122.
Let
P(Z<0.3206)= 0.6257, P(Z<0.5496)= 0.7087, P(Z<2.6359) = 0.9958, P(Z< 1.5376) = 0.9381
A. 0.0833
