1. The problem statement, all variables and given/known data Find Z0 such that P(z > z0) = 0.1234 2. Relevant equations 3. The attempt at a solution Z is the mean which is 0. So if Z0 is less than the mean it should be a negative number. Looking at the table 0.1234 does not show up but the closest is 0.1217 which is 0.31. So Z0 is -0.31?
