Test of hypothesis for the ratio between two variances.
Hypotheses value and 95% CIConclusion
H01: the variance in the accuracy for CS equals the variance in the accuracy for OS; .
H11: the variance of accuracy for CS is less than the variance of accuracy for OS; .		0.008 [0.1 ∞)There is statistical evidence that the variance in the accuracy for CS is less than the variance in the accuracy for OS by a factor of 0.1.
H02: the variance in the accuracy for DA equals the variance in the accuracy for DA/CS; .
H12: the variance in the accuracy for DA is more than the variance in the accuracy for DA/CS; .		0.001 [2.3 ∞)There is statistical evidence that the variance in the accuracy for DA is more than the variance in the accuracy for DA/CS by a factor of 2.3.
H03: the variance in the accuracy for DA/CS equals the variance in the accuracy for OS; .
H13: the variance in the accuracy for OS is more than the variance in the accuracy for DA/CS; .		0.003 [2.2 ∞)There is statistical evidence that the variance in the accuracy for OS is more than the variance in the accuracy for DA/CS by a factor of 2.2.
