Power versus fold change for two key contrasts. The figure plots the power for a two-sided t-test at the 0.002 significance level as a function of the fold change. Blue lines give the power for a sex difference within a sacrifice time, and red lines give the power for a difference between two AZT levels within a sex and sacrifice time. Solid lines use the error for Option 1 (Table 3) and the dashed lines use the error for Option 2 (Table 4).
