4. A population consists of five values ( 5, 9, 13, 17. 21). A sample of size 2 is to be taken from the population. Verify the Central Limit Theorem by: a. Compute the variance (2 )and standard deviation ( 2) of the population b. Compute the variance (2 ) and the standard deviation (62 ) of the sampling deistribution of the sample mean c.
