A random sample of n = 226 measurements is drawn from a binomial population with probability of success 0.85. Complete parts a through c below.a. Find Eē) and onThe mean of the sampling distribution of pisThe standard deviation of the sampling distribution of pis(Round to four decimal places as needed.)b. Describe the shape of the sampling distribution of P.O A. The shape of the sampling distribution of Pis approximately normal because the sample size is large.OB. The shape of the sampling distribution of Dis approximately normal because the sample size is small.O C. The shape of the sampling distribution of Dis approximately uniform because the sample size is small.OD. The shape of the sampling distribution of is approximately uniform because the sample size is large.C. Find P<0.9)The probability that is less than 0.9 is(Round to four decimal places as needed.)
