Answer #1
Given,
= 14 , 
= 1.1
Mean of sampling distribution of 
=
= 14
Standard deviation of sampling distribution of
=
=
/ sqrt(n)
= 1.1 / sqrt(40)
= 0.1739

The amount of money collected by a snack bar at a large
university has been recorded daily for the past five years. Records
indicate that the mean daily amount collected is $3250 and the
standard deviation is $400. The distribution is skewed to the right
due to several high volume days (including football game days).
Suppose that 60 days were randomly selected from the five years and
the average amount collected from those days was recorded. Which of
