Quizplus · Accepted Answer

The reciprocal of the F-value that divides the area under the curve into a middle 0.99 area and two outside 0.005 areas is the F-value that divides the area under the curve into a middle 0.01 area and two outside 0.995 areas. Using the F-table, we find that the F-value that divides the area under the curve into a middle 0.01 area and two outside 0.995 areas is 6.42. Therefore, the reciprocal of this F-value is 0.156.
