WebAssuming you’re conducting a two-tail test, subtract alpha divided by 2 from 1. Then find the closest probability value in the Z score table and add your Z score row + column. For example, when you’re trying to find a Z score for a two tail test at alpha = .05. 1- (.05/2) = .975. On the 1.9 row and the .06 column, you will find .9750. dogfish tackle \u0026 marine
