Suppose a simple random sample of size n= 36 is obtained from a population with u = 73 and c = 12. (a) Describe the sampling distribution of X (b) What is PX>75.1)? (c) What is P (XS68.5) ? (d) What is P (71.9<x< 76) ?

O A. The distribution is skewed right. OB. The distribution is skewed left OC. The distribution is uniform. OD. The distribution is approximately normal. O E. The shape of the distribution is unknown. Find the mean and standard deviation of the sampling distribution of x. (b)P (>75.1) = (Round to four decimal places as needed.) (c) P (X568.5) - (Round to four decimal places as needed.) (d) P (71.9<3<76) - (Round to four decimal places needed.)
