Describe the sampling distribution of p. Assume the size of the population is 20,000. n = 500, p =0.6 Choose the phrase that best describes the shape of the sampling distribution of p below. O A. Not normal because n $ 0.05N and np(1 - p) 2 10. O B. Approximately normal because n = 0.05N and np(1 - p) 2 10. O C. Approximately normal because n $ 0.05N and np(1 - p)
