Explain question 3 and 4 (main part idonycomprehed )

5. Suppose that we have a population distribution with u = 50 and o = 4.0. The following ten samp le distributions are drawn from the population. The sample size of each is 20. (2 X 4 = 8 points) T Sample Mean SD 5.3 50 6.5 NM 64 58 4.2 60 4.5 2.9 4.3 5.5 the NOOr - 3.8 1 11700 D 3.7 4.9 2 (1) What is this distribution of the sample means called? 2 Za T (2) Compute the mean of this distribution (the mean of the sample,means). (3) Compute the standard error of the empirical sampling distribution. (4) Compute the standard error of the theoretical sampling, distribution, 73. 11 listribution in which u = 7.0 and o = 2.5
