The finishing time for cyclists in a race have an unknown distribution with mean $_138$_ and standard deviation $_13$_ minutes. A sample, with size $_n = 42$_, was randomly drawn from the population. Using the Central Limit Theorem for Means, what is the mean for the sample mean distribution?

Expert Solution
Step 1: Determine the given data in the question

Let X be the random variable that is the finishing time for cyclists in a race.

Given that,

P o p u l a t i o n space m e a n space left parenthesis mu right parenthesis equals 138
P o p u l a t i o n space s tan d a r d space d e v i a t i o n space left parenthesis sigma right parenthesis equals 13
S a m p l e space s i z e space left parenthesis n right parenthesis equals 42
