The stud) provided the following information on the distribution of levels of support for sustainability: µ = 68, σ = 27. Now consider a random sample of 45 senior managers and let  represent the sample mean level of support.
a. Give the value of µ, the mean of the sampling distribution of , and interpret the result.
b. Give the value of σ, the standard deviation of the sampling distribution of , and interpret the result.
c. What does the Central Limit Theorem say about the shape of the sampling distribution of 
d. Find P( > 65).
