Suppose a simple random sample of size n = 36 is obtained from a population that is skewed right with p=87 and o=18
(a) Describe the sampling distribution of x.
(b) What is P (x>92.25)?
(c) What is P (x≤79.65) ?
(d) What is P (85.2 <x< 94.05) ?
B. The distribution is approximately normal.
OC. The distribution is skewed left.
OD. The distribution is skewed right.
