Question
Assume that women's heights are normally distributed with a mean given by mu equals 63.6 in, and a standard deviation given by sigma equals 2.5 in.
(a) If 1 woman is randomly selected, find the probability that her height is less than 64 in. (b) If 43 women are randomly selected, find the probability that they have a mean height less than 64 in. (a) The probability is approximately . 5636. (Round to four decimal places as needed.)
(b) The probability is approximately nothing. (Round to four decimal places as needed.)
Still having trouble. Could I get a solution for this problem of (c). Plus more detail on what to do with the 5%'s. Thanks.
