Suppose that we will take a random sample of size n from a population having mean µ and standard deviation σ. For each of the following situations, find the mean, variance, and standard deviation of the sampling distribution of the sample mean: (a) µ = 19, σ = 6, n = 47 (b) µ = 488, σ = .3, n = 147 (c) µ = 7, σ = 1.0, n = 5 (d) µ = 143, σ = 6, n = 1,378

Suppose that we will take a random sample of size n from a population having mean µ and standard deviation σ. For each of the following situations, find the mean, variance, and standard deviation of the sampling distribution of the sample mean:

(a) µ = 19, σ = 6, n = 47

(b) µ = 488, σ = .3, n = 147

(c) µ = 7, σ = 1.0, n = 5

(d) µ = 143, σ = 6, n = 1,378
