Suppose a simple random sample of size n= 125 is obtained from a population whose size is N = 25,000 and whose population proportion with a specified characteristic is p = 0.8. Complete parts (a) through (c) below. (b) What is the probability of obtaining x = 105 or more individuals with the characteristic? That is, what is P(p20.84)? P(p 20.84) = 0.1318 (Round to four decimal places as needed.) (c) What is the probability of obtaining x = 90 or fewer individuals with the characteristic? That is, what is P(ps0.72)? P(ps0.72) = (Round to four decimal places as needed.)
