a) Even though the sample size is not large enough, use the CLT to estimate the

probability that the sample mean is greater than 2.

b) Compute the exact probability that the sample mean is greater than 2.

c) Repeat (a) and (b), for a sample of size 64. Is your approximation closer than it

was for a sample of size 16?

How do you find sample mean and sample variance to plug into the CLT?
