I understand that if one man is selected the probability his weight is less than 182 lbs is .6331
However I don't understand if 25 men are randomly selected what is the probability that they have a mean weight less than 182 lbs.
I know the answer is .9573 but I do not understand how to get it.

The expert understands the z score using the Central Limit Theorem.
