7..3.6. If *Y *is a chi square random variable with *n *degrees of freedom, the pd! of (*Y** *- n);*./ii,** *converges to *.fz *(z) as *n *goes to infinity (recall Question 7.3.2). Use the asymptotic normality of *( Y *- *n)J./2n *to approximate the fortieth percentile of a ch i square random variable with 200 degrees of freedom.

7.3.7. Use Appendix Table A.4 to find

(a) *F*5-0.6,7

(b) *F.001,15,5*

(c) F.90,2.2

7.J.8. Let *V** *and *U** *be independent chi square random variables with 7 and *9** *degrees of freedom, respecth,:ely. *Is** *it more likely that ;;will be between (1) 2.51 and 3.29 or (2) 3.29 and 4.20?
