A simple random sample of size n = 150 is obtained from a population whose size is N = 10,000 and whose population proportion with a specified characteristic is p = 0.6.
(a) Describe the sampling distribution of pn.
(b) What is the probability of obtaining x = 93 or more individuals with the characteristic? That is, what is P1pn Ú 0.622?
(c) What is the probability of obtaining x = 81 or fewer individuals with the characteristic? That is, what is P1pn … 0.542?
