Describe the sampling distribution of p. Assume the size of the population is 15,000. n 500, p 0.5 Choose the phrase that best describes the shape of the sampling distribution of p below. O A. Not normal because n s 0.05N and np(1 -p)10. O B. Not normal because n s 0.05N and np(1 -p) 10. ° C. Approximately normal because n s 0.05N and np(1-p) < 10. O D. Approximately normal because n s 0.05N and np(1 p)a 10. Determine the mean of the sampling distribution of p. μ,-| 0.5 | (Round to one decimal place as needed.) Determine the standard deviation of the sampling distribution of p. ơ,- (Round to three decimal places as needed.)
