thx you!!!!

Suppose a simple random sample of size n = 49 is obtained from a population that is skewed right with u = 80 and o = 21. (a) Describe the sampling distribution of x. (b) What is P (x > 85.4) ? (c) What is P (x $ 72.8) ? (d) What is P (75.5 85.4) = (Round to four decimal places as needed.) (c) P (x$72.8) = (Round to four decimal places as needed.) (d) P (75.5
