A researcher conducts a repeated-measures study to evaluate the efficacy of therapy in decreasing maladaptive behavior. The researcher examines maladaptive behavior before and after therapy with a sample of n = 6 participants and obtains a sample mean difference of MD = 6 with an estimated standard error of sMD = 3.00. Which of the following is the correct decision for a one-tailed hypothesis test in which therapy is expected to reduce maladaptive behavior? a. reject the null hypothesis with α = .05 but not with α = .01 b. reject the null hypothesis with both α = .05 and α = .01 c. fail to reject the null hypothesis with both α = .05 and α = .01 d. fail to reject the null hypothesis with α = .05 but not with α = .01
