| Sep 2, 2015 at 6:01 | comment | added | user3275222 | I didn't calculate power. In SAS, you are required to add this term, I quote from their manual: "An analysis of confidence interval precision is analogous to a traditional power analysis, with CI Half-Width taking the place of effect size and Prob(Width) taking the place of power". Where in my way, the power doesn't exist, as all I do, is to play with the CI formula to extract N for the highest desired mu - Xbar value. | |
| Sep 2, 2015 at 4:54 | comment | added | Deep North | Which formula did you use to calculate the power? probably I can show you they are the same. | |
| Sep 2, 2015 at 4:40 | comment | added | user3275222 | But they yield different N's, and in SAS I need to specify a "power", in my way I don't. It must take a role in the calculations. If we simplify and take Z for a second, then all I do is a bit of algebra. I do not have a power term in my formula. | |
