ANOVA

Hello. I have finished all of my homework except for these two questions. I need step-by-step solutions for these two problems, so that I can do the other questions like them in future homework assignments. I have erased all of the questions on here and I am attaching a file which has the questions on it.

1) An experimenter has investigated the effects of cigarette smoking on learning. Two levels of the smoking variable were used (smoked, did not smoke). There are also two levels of the learning variable (intentional learning and incidental learning).
(A) Practice the two-way between-subjects ANOVA on these data.
(B) Interpret the main effects and interaction of this experiment.
Factor 1 (Smoking)
Smoked Did not smoke
Factor 2 (Learning) Intentional 4 5
3 4
5 (M = 4) 4 (M = 4.2)
4 3
4 5
Incidental 3 4
2 3
2 (M = 2.4) 4 (M = 3.2)
3 3
2 2

2) Practice carrying out the one-way ANOVA procedures by calculating the F ratio for these data. The hypothetical scores below represent the responses of subjects in four treatment groups who were given four different driver education programs. The dependent variable is the subjects' errors on their state examinations for drivers' licenses.

Group 1 Group 2 Group 3 Group 4
3 1 1 2
3 2 1 3
1 1 3 2
3 4 1 5
1 2 2 1
