7. The test scores for the Law School Admission test (LSAT) in a recent year are normally

distributed, with a mean of 155.69 and a standard deviation of 5.05. Random samples of size

40 are drawn from this population and the mean of each sample is determined. What is the

mean and the standard deviation of the sampling distribution of sample means?

(a) = 155.69, = 5.05

(b) = 155.69, 0.80

(c) = 40, = 5.05

(d) = 40, 0.80

(e) = 155.69, = 5.05
