1. For males the expected pulse rate is 70/m and the standard deviation is 10/m. For women the expected pulse rate is 77/m and the standard deviation is 12/m. Let X be the sample average pulse rate for a random sample of 80 men and let Y be the sample average pulse rate for a random sample of 100 women. (a) Specify the approximate distribution of X and Y (asymptotically).
