Please consider the following information: Sample mean (M) = 52 Population mean (P) = M = 49 Sample standard deviation (s) = 15 Sample size (N) = 81 If a researcher used the information listed above and conducted a two-tailed hypothesis test with an alpha level (p level) of 0.05 (5%), should the researcher reject a typical null hypothesis of no differences between population means, based on the corresponding t test and the rules of hypothesis testing?
