Suppose a simple random sample of size n = 1000 is obtained from a population whose size is N = 2,000,000 and whose population proportion with a specified characteristic is p = 0.75. Complete parts (a) through (c) below. ..... (a) Describe the sampling distribution of p. O A. Approximately normal, µ. = 0.75 and on x0.0003 O B. Approximately normal, µa = 0.75 and oa x 0.0002 O C. Approximately normal, Ha = 0.75 and g. x 0.0137 (b) What is the probability of obtaining x= 780 or more individuals with the characteristic? P(x2 780) = (Round to four decimal places as needed.) (c) What is the probability of obtaining x= 730 or fewer individuals with the characteristic? P(xs730) = (Round to four decimal places as needed.)
