Assume that women's heights are normally distributed with a mean given by u = 62.8 in, and a standard deviation given by a = 2.6 in. Complete parts a and b. a. If 1 woman is randomly selected, find the probability that her height is between 62.2 in and 63.2 in. The probability is approximately 0.1523 . (Round to four decimal places as needed.) b. If 20 women are randomly selected, find the probability that they have a mean height between 62.2 in and 63.2 in. The probability is approximately . (Round to four decimal places as needed.)
