You are performing a two-tailed z test. If α = .004 , find the positive critical value rounded to two decimal places.
A researcher is using a two-tailed hypothesis test with α = .05 to evaluate the effect of a treatment. If the boundaries for the critical region are t = ± 2.080, then how many individuals are in the sample? n = 20 n = 22 n = 21 Impossible to determine without more information
