In Exercises, use Table VIII and, if necessary, the reciprocal property of F-curves to find the required F-values. Illustrate your work graphically.

Determine the two F-values that divide the area under the curve into a middle 0.95 area and two outside 0.025 areas for an F-curve with

a. df = (7, 4).

b. df = (12, 20).
