Answer #1

(a) one-factor ANOVA

Explanation: We use paired t test for checking the significant difference in the two paired population means. We use the one factor ANOVA test for checking the significant differences in the three or more population means. We use the two factor ANOVA test for checking the significant differences within treatments and among treatments, and also checking significant interactions. So, for checking only significant differences between three or more population means, we use one factor ANOVA.
