Solved: Finding Critical Values In constructing confidence

Chapter 7, Problem 23

(choose chapter or problem)

Finding Critical Values In constructing confidence intervals for s or s2, Table A-4can be used to find the critical values x2L and x2R only for select values of n up to 101, so thenumber of degrees of freedom is 100 or smaller. For larger numbers of degrees of freedom, wecan approximate x2L and x2R by usingx2 = 123{za>2 + 22k - 14 2where k is the number of degrees of freedom and za/2 is the critical z score described inSection 7-2. Use this approximation to find the critical values x2L and x2R for Exercise 9. How dothe results compare to the actual critical values of 82.354 and 129.918?
