pls help...

C. Samples of size n were randomly selected from populations with means (with replacements) and variances given below. In each case, find the mean and standard deviation of the sampling distribution of the means. 1. n = 4 M = 4.7 02 = 3 2. n = 7 1 = 4 02 = 2 3. n = 16 1 =7 02 = 6 4. n = 22 u = 22 02 = 4.5 5. n = 44 4 = 40 02 = 9.6
