I need help finding out if my answer here is right or wrong

Means of one group, means of another group *d. Group means, grand mean 7.6. The formula for the F ratio involves dividing a by a . (Fill in the blanks.) a. Sum of square, mean square b. Mean square, sum of square *c. Mean square, mean square d. Mean square, sum of squares 7.7. If the null hypothesis in an ANOVA situation were true, over the long run the value of F would be: a. Zero *b. One c. Depends on degrees of freedom d. Depends on what type of ANOVA it is 7.8. An independent groups t-test is to a dependent groups t- test as is to . (Fill in the blanks.) *a.

Factorial design 7.11. If a researcher found a significant interaction effect, it would mean that: a. Both of the main effects were also significant b. Neither of the main effects was significant *c. The means for different levels of one variable were not consistent across different levels of another d. The means for one variable were different from the means for the second variable 7.12.
