Assume that women's heights are normally distributed with a mean given by u=64.7 in , and a standard deviation given by 2.8 in . (a) If 1 woman is randomly selected, find the probability that her height is between 64.4 in and 65.4 in. The probability is approximately 0.1521 b) If 13 women are randomly selected, find the probability that they have a mean height between 64.4 in and 65.4 in. The probability is approximately 0.4955
