I’m trying to calculate minimum sample sizes for a A/B hypothesis test . I hypothesizing a 10% decrease based on a historical benchmark of 5%. How to you write the syntax for this. The below is not correct. Sides=L makes sense to me but in the GroupProportions = ( 0.05 -0.05) the -0.50 is is casuing an error.
Any assistance will be greatly appreciated!
Alpha = 0.01
Sides = L
GroupProportions = ( 0.05 -0.05)

A proportion is a number 0 < p < 1. Try
groupproportions = (0.15 0.05)
