# Question: For each of the following combinations of a and degrees

For each of the following combinations of a and degrees of freedom (df), use Table VII in Appendix B to find the values of x2α/2 and, x2(1-α/2) that would be used to form a confidence interval for σ2.

a. α = .05, df = 7

b. α = .10, df = 16

c. α = .01, df = 20

d. α = .05, df = 20

a. α = .05, df = 7

b. α = .10, df = 16

c. α = .01, df = 20

d. α = .05, df = 20
