A researcher evaluates the effectiveness of special mindfulness exercises improve memory. For her study, she uses a one-tailed hypothesis test with a = .05, and the decision is to reject the null hypothesis. If the researcher switched to a two-tailed test using the same sample, what decision would be made? Definitely reject the null hypothesis with a = .05 and maybe reject with a=.01 Might reject the null hypothesis with a = .05 but might not Definitely reject the null hypothesis with either a = .05 or with a = .01 Definitely fail to reject the null hypothesis with either a = .05 or with a = 01
