Suppose that we will take a random sample of size n from a population having mean ? and standard deviation o. For each of the following situations, find the mean, variance, and standard deviation of the sampling distribution of the sample mean : 2" (a) ? = 19, o = 6, n = 47 (Round your answers of "o " and "o to 4 decimal places.) X ux Ox^2 ox 211 (b) ? = 488, o = .3, n = 147 (Round your answers of "o " and "c "0 X ?x Ox^2 ?? X to 4 decimal places.)

Solution:- Given that, a sample of size n is taken from population with mean, and standard deviation, Consider the Central Limit Theorem, CLT as below:- Central Limit Theorem, CLT:- This theorem states that if the sample drawn is larger than 30 or th
