A researcher administers a treatment to a sample of n = 25 participants and uses a hypothesis test to evaluate the effect of the treatment. The hypothesis test produces a z-score of z = 2.37. Assuming that the researcher is using a two-tailed test, what decision should be made? The researcher should reject the null hypothesis with either ? = .05 or ? = .01. The researcher should reject the null hypothesis with ? = .05 but not with ? = .01.     Cannot answer without additional information. The researcher should fail to reject H0 with either ? = .05 or ? = .01.
