- Determine the critical value z a/2Determine the upper-tail critical value tα/2 in each of the following circumstances.With α = .05 and df = 8, the critical values for a two-tailed t-test are t = ±2.306. Assuming all other factors are held constant if the df value were decreased to df = 5, what would happen to the size of the critical regions?
