Assume that women's heights are normally distributed with a mean given by μ = 63.5 in, and a standard deviation given by o = 1.7 in. (a) If 1 woman is randomly selected, find the probability that her height is less than 64 in. (b) If 34 women are randomly selected, find the probability that they have a mean height less than 64 in. (a) The probability is approximately. (Round to four decimal places as needed.)
