In a sample of n = 100 people, 35 preferred brand A and 65 preferred brand B. Assuming that the researcher uses a two-tailed test, what is the appropriate statistical decision? O Reject the null hypothesis with a = .05 but not with a = .01. O Reject the null hypothesis with either α = .05 or α = .01. O Fail to reject the null hypothesis with either a = .05 or α = .01. O No decision is possible without additional information.
