Question
Problem 6 From Devore, page 314, do the following problem 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 devi- ation is 12/m. Let x-the sample average pulse rate for a random sample of 40 men and letY the sample average pulse rate for a random sample of 36 women a. What is the approximate distribution of X? Of Y? b. What is the approximate distribution of X-Y? c. Calculate (approximately) the probability d. Calculate (approximately) P(X - YExplanation / Answer
