Assume that women’s heights are normally distributed with a mean given by μ=63.5 in, and a standard deviation given by σ=3.1 in.
a. If 1 woman is randomly selected, find the probability that her height is less than 64 in.
The probability is approximately .
b. If 44 women are randomly selected, find the probability that they have a mean height
less than 64 in.
The probability is approximately .
