SAMPLING DISTRIBUTION(Find and construct a table of mean and variance of samplingdistribution of sample mean.)Problem: A population consists of the numbers 2, 4, 9, 11,and 12. Let us list all possible sample size of 3 from thispopulation and compute the mean and variance of the samplingdistribution of sample means.

Total number of samples of size 3 from a population of size 5 is: 5C3 = 10

(a) Does the population have to be normally distributed to test this hypothesis? Why? A. No, because n2 30. B. Yes, because n2 30. C. Yes, because the sample is random. D. No, because the test is two-tailed. (b) If x = 99.8 and s = 5.9, compute the test statistic. The test statistic is to =. (Round to two decimal places as needed.)
