4. 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 1.77. Assuming that the researcher is using a two-tailed test, Z-score of z a. The researcher should reject the null hypothesis with a = .05 but not with a = .01. b. The researcher should reject the null hypothesis with either a = .05 or a = .01. c. The researcher should fail to reject H, with either a = .05 or a = .01. %3D d. Cannot answer without additional information.
