Choose the most appropriate Stata command to use if I want to investigate the simple effect of sex while maintaining good power to detect any effects: O a. contrast sex@pints, effects mcompare (bon) O b. contrast pints@sex, effects mcompare (bon) O c. contrasts sex, effects mcompare (bon) O d. pwcompare sex#pints, effect mcompare (bon) . anova pints@sex, effects mcompare (bon). anova anxiety sex##pints Number of obs = 48 R-squared = 0.7423 Root MSE 9.29366 Adj R-squared = 0.7116 Source Partial SS df MS F Prob>F Model 10450.688 5 2090.1375 24.20 0.0000 sex 1.0208333 1. 0208333 0.01 0.9139 pints 9330.125 4665.0625 54.01 0.0000 Sex#pints 1119.5417 2 559.77083 6.48 0.0035 Residual 3627.625 42 86.372024 Total 14078.313 47 299.53856
