Question
Suppose a simple random sample of size n= 1000 is obtained from a population whose size is N = 1,500,000 and whose population proportion with a specified characteristic is p = 0.76. Complete parts (a) through (c) below. (a) Describe the sampling distribution of p. O A. Approximately normal, µa = 0.76 and on 0.0135 O B. Approximately normal, µa = 0.76 and on 0.0003 C. Approximately normal, µa = 0.76 and on 0.0002 (b) What is the probability of obtaining x = 780 or more individuals with the characteristic? P(x2780) = (Round to four decimal places as needed.) (c) What is the probability of obtaining x = 720 or fewer individuals with the characteristic? P(xs720) = (Round to four decimal places as needed.)
