## What is the mean in this problem?

In a particular basketball league, the standard deviation in the distributionleague average height

of players' height is 2 inches. Twenty- five players are selected at random

and their heights are measured. Give an estimate for the probability that

the average height of the players in this sample of 25 is within 1 inch of the

This is a central limit theorem problem.Here variance of 25 players = (S.D.)^2/n

=4/25

and therefore S.D. of 25 players = 2/5

but what about mean ????
