Suppose a simple random sample of size n= 150 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. n (a) Describe the sampling distribution of P. Choose the phrase that best describes the shape of the sampling distribution below. A. Approximately nomal because ns0.05N and np(1-P) 10. B. Not normal because ns0.05N and np(1-P)< 10, OC. Not normal because ns0.05N and np(1-P)2 10 OD. Approximately normal because ns0 05 and np(1-P)< 10 Determine the mean of the sampling distribution of (Round to one decimal place as needed.) Determine the standard deviation of the sampling distribution of p. (Round to six decimal places as needed) (b) What is the probability of obtaining x= 126 or more individuals with the characteristic? That is what is P© 20.84)? [email protected])=(Round to four decimal places as needed) (c) What is the probability of obtaining x = 108 or fewer individuals with the characteristic? That is what is Pros 072) PÖs0.72)-(Round to four decimal places as needed.) HA =
