In each of the following cases, find the mean, variance, and standard deviation of the sampling distribution of the sample proportion 8. (a) p= .7, n = 251 (Round varlance to 6 decimal places and standard deviation to 4 decimal places. Do not round Intermediate values.) (p-hat) p o(p-hat)^2 o(p-hat) (b) p = 3, n=129 (Round variance to 6 decimal places and standard deviation to 4 decimal places. Do not round Intermediate values.) p(p-hat) p o(p-hat)^2 o(p-hat) (c) p= .7, n=407 (Round varlance to 6 decimal places and standard deviation to 4 decimal places. Do not round Intermediate values.) (p-hat) = p o(p-hat)^2 o(p-hat) (d) p= .88, n=982 (Round varlance to 6 decimal places and standard deviation to 4 decimal places. Do not round Intermediate values.) |p(p-hat) = p o(p-hat)^2 o(p-hat)
