How about considering an alternative hypothesis, along
Giroux's lines? The power of a statistical test is the probability of rejecting
the null hypothesis given that the alternative hypothesis is true
(Cohen, 1988; Kraemer & Thiemann, 1987; Lipsey, 1990). In this situation, the null hypothesis is that the
tumor incidence rates in the dose groups are no larger than the rate in
the control group; the alternative hypothesis is that the tumor
incidence rate in at least one dose group is strictly larger than in the
control group. |
