Test 1: ; Test 2: ; Test 3: . For each hypothesis test, reject if the Bonferroni-adjusted . Test 1: ; Test 2: ; Test 3: . Test 1: Bonferroni-adjusted ; Test 2: Bonferroni-adjusted ; Test 3: Bonferroni-adjusted . Test 1: The adjusted , which is not ; therefore we do not reject . There is insufficient evidence at the level of significance that the population mean of Population A differs from the population mean of Population B. Test 2: The adjusted , which is not ; therefore we do not reject . There is insufficient evidence at the level of significance that the population mean of Population A differs from the population mean of Population C. Test 3: The adjusted , which is ; therefore we reject . There is evidence at the level of significance that the population mean of Population B differs from the population mean of Population C.
