Assume that n eight-sided dice are rlled ma times and the mean of the n outcomes is computed each time b. Find the mean and standard deviation of the resulting distribution of sample means for n 144 The mean of the resulting distribution of sample means is 4.5 (Round to the nearest tenth as needed) The standard deviation of the distribution of sample means is (Round to the nearest thousandth as needed) Enter your answer in the answer box and then click Check Answer part emainina 24/201 0 Type here to search

Explanation / Answer

B) Standard deviation of sampling distribution = population standard deviation /sqrt(n) = 2.291 / sqrt(144) = 0.191
