Give the mean and standard deviation of the sampling distribution of the sample proportion, p. The mean of the sampling distribution of pis The standard deviation of the sampling distribution of p is. (Round to four decimal places as needed.) b. Describe the shape of the sampling distribution of p. OA. The shape of the sampling distribution of p is approximately normal because the sample size is large. OB. The shape of the sampling distribution of p is approximately uniform because the sample size is large. OC. The shape of the sampling distribution of p is approximately normal because the sample size is small. OD. The shape of the sampling distribution of p is approximately uniform because the sample size is small. c. Calculate the standard normal'z-score corresponding to a value of p=0.32. The standard normal z-score corresponding to a value of p=0.32 is. (Round to two decimal places as needed.) 2 Weeks
