Suppose babies born in a large hospital have a mean weight of 4088 grams, and a variance of 55,696. If 128 babies are sampled at random from the hospital, what is the probability that the mean weight of the sample babies would be less than 4132 grams? Round your answer to four decimal places.

0.0107

Explanation:

We were told that 128 babies are sampled at random from the hospital, which implies that there are 128 sample size, then , (n = 128)

Given from the question;

mean weight =4088

variance = 55,696

We need to determine probability that the mean weight 4088

would be less than 4132 grams

P = 1 - (4088/4132)

P = 1-0.9893

=0.0107
