Explain.Step 1(a) Describe the x distribution and compute the mean and standard deviation of the distribution.The central limit theorem states that when the sample size n is 30 or larger, the x distribution isapproximately normal. Here we are given n = 81 and since 81 > 30 we can say that the x distribution isapproximately normal.We are given that the x distribution has mean 55. Since the distribution is approximately normal we haveH =SubmitSkip (you cannot come back).

Suppose x has a distribution with a mean of 55 and a standard deviation of 18. Random samples of size n = 81 are drawn. (a) Describe the x distribution and compute the mean and standard deviation of the distribution. (b) Find the z value corresponding to x = 52. (c) Find P( < 52). (d) Would it be unusual for a random sample of size 81 from the x distribution to have a sample mean less than 52? Explain.

8. In an educational research project it is necessary to construct a controlgroup that shares some features with the experimental group. Thereare 12 children in the experimental group, and the investigator decidesthat the control group should be the same size.The mean and the variance of the variable x in the experimental groupare 6.0 and 14.00, respectively. The investigator wishes to constructthe control group so that both groups will have the same mean andvariance.After ten children have been selected for the control group, the mean oftheir -values is 5.8 and the variance is 16.36. Two additional childrenwill be selected for the control group.What should the -values of these children be so that the experimen-tal group and the control group have equal means and variances?
