What can you do with the ANOVA test that you cannot do with the t-test?     the ANOVA allows us to test two items where the t-test allows testing for more than two items     there is no difference between what the t-test and the ANOVA can test     the ANOVA can test for two items and the t-test can test for one item     the ANOVA allows us to test more than two items, where the t-test can only test two items

All other factors the same, as the sample size increases, the margin of error O decreases O stays the same O increases
