Suppose a simple random sample of size n = 150 is obtained from a population whose size is N= 15,000 and whose population proportion with a specified characteristic is p =0.4. Complete 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. Not normal because n s 0.05N and np(1 - p) 10. Determine the mean of the sampling distribution of p. HA = 0.4 (Round to one decimal place as needed.) Determine the standard deviation of the sampling distribution of p. GA = 0.040000 (Round to six decimal places as needed.) (b) What is the probability of obtaining x = 69 or more individuals with the characteristic? That is, what is P(p 2 0.46)? P(p 2 0.46) = (Round to four decimal places as needed.)
