[Solved] What would happen if instead of using an ANOVA to compare 10 groups, you performed multiple ttests?

Q.	What would happen if instead of using an ANOVA to compare 10 groups, you performed multiple ttests?
A.	Nothing, there is no difference between using an ANOVA and using a t-test.
B.	Nothing serious, except that making multiple comparisons with a t-test requires more computation than doing a single ANOVA.
C.	Sir Ronald Fischer would be turning over in his grave; he put all that work into developing ANOVA, and you use multiple t-tests
D.	Making multiple comparisons with a t-test increases the probability of making a Type I error.
Answer» D. Making multiple comparisons with a t-test increases the probability of making a Type I error.

An investigator randomly assigns 30 college students into three equal size study groups (early-morning, afternoon, late-night) to determine if the period of the day at which people study has an effect on their retention. The students live in a controlled environment for one week, on the third day of the experimental treatment is administered (study of predetermined material). On the seventh day the investigator tests for retention. In computing his ANOVA table, he sees that his MS within groups is larger than his MS between groups. What does this result indicate?
You carried out an ANOVA on a preliminary sample of data. You then collected additional data from the same groups; the difference being that the sample sizes for each group were increased by a factor of 10, and the within-group variability has decreased substantially.

You obtained a significant test statistic when comparing three treatments in a one-way ANOVA. In words, how would you interpret the alternative hypothesis HA?
If the sample means for each of k treatment groups were identical (yes, this is extremely unlikely), what would be the observed value of the ANOVA test statistic?
