Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean |J=152 days and standard deviation 0': 10 days. Complete parts (a) through (f) below. (f) What is the probability a random sample of size 17 will have a mean gestation period within 8 days of the mean? The probability that a random sample of size 17 will have a mean gestation period within 8 days of the mean is (Round to four decimal places as needed.)
