Suppose a simple random sample of size n=49 is obtained from a population with μ=79 and o=21. (a) Describe the sampling distribution of x (b) What is P (76<x<86.5)? OA. The distribution is uniform. OB. The distribution is skewed left. C. The distribution is approximately normal. OD. The distribution is skewed right. OE. The shape of the distribution is unknown. Find the mean and standard deviation of the sampling distribution of x. "x =79 ox 3.0 (b) P (76<x<86.5) = (Round to four decimal places as needed.) 2
