WebThe middle part, inside of the critical values, must be the confidence level. The two tails must combine to be α, so each tail is α/2. Hence, for a 95% confidence interval, instead of looking up 0.05 or 0.95, we want to look up 0.25 or 0.975 in the Z-table, and get the Z critical values from those.
