1. (Easiest Way) Use known values for z alpha/2. You don’t actually have to look up z alpha/2 in a z-table every time. For most hypothesis tests, you’ll probably be using one of four confidence levels (90%, 95%, 98% and 99%). The z alpha/2 for each confidence level is always the same: 2. Use a Z-Table. Step 1: Find the alpha level.
