Problem 5E

Let X1,X2, . . . ,X18 be a random sample of size 18 from a chi-square distribution with r = 1. Recall that

μ = 1 and σ2 = 2.

(a) How is  distributed?

(b) Using the result of part (a), we see from Table IV in Appendix B that P(Y ≤ 9.390) = 0.05 and P(Y ≤ 34.80) = 0.99.Compare these two probabilities with the approximations found with the use of the central limit theorem.
