Suppose a simple random sample of size n= 125 is obtained from a population whose size is N= 30,000 and whose population proportion with a specified characteristic is p = 0.6. Complet parts (a) through (c) below. (a) Describe the sampling distribution of p. Choose the phrase that best describes the shape of the sampling distribution below. O A. Approximately normal because ns0.05N and np(1- p) 2 10. O B. Approximately normal because ns0.05N and np(1- p) < 10. O C. Not normal because ns0.05N and np(1- p) 2 10. O D. Not normal because ns0.05N and np(1 - p) < 10. Determine the mean of the sampling distribution of p. = (Round to one decimal place as needed.) Determine the standard deviation of the sampling distribution of p. (Round to six decimal places as needed.)

Question

Suppose a simple random sample of size n = 125 is obtained from a population whose size is N = 30,000 and whose population proportion with a specified characteristic is p = 0.6

(b) What is the probability of obtaining x = 80 or more individuals with the characteristic? That is, what is P(p20.64)? P(p20.64) =O (Round to four decimal places as needed.) (c) What is the probability of obtaining x= 65 or fewer individuals with the characteristic? That is, what is P(ps0.52)? P(ps0.52) =(Round to four decimal places as needed.)
