Assume that women's heights are normally distributed with a mean given by mu equals 63.2 in, and a standard deviation given by sigma equals 2.1 in. complete parts a and b. a. if 1 woman is randomly selected, find the probability that her height is between 62.4 in and 63.4 in. the probability is approximately . 1863. (round to four decimal places as needed.) b. if 7 women are randomly selected, find the probability that they have a mean height between 62.4 in and 63.4 in

a. Your answer is correct.

b. Divide the given value of sigma by √n where n = sample size = 7. Then perform the same calculation you did for part a. The probabiilty is 0.4427.

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question
