1. To answer this question, refer to the following hypothetical data collected using replicated measures design.

Subject	1	2	3	4	5	6	7	8	9	10
Pre	50	49	37	16	80	42	40	58	31	21
Post	56	50	30	25	90	44	60	71	32	22

A. In a two-tailed test of H 0 using α=0.05, what is p(obtained) for the results shown? *Hint: "two-tailed" means the same thing as nondirectional. ANSWER = 0.0216

B. What would you conclude regarding H0 using a = 0.05 2-tail? ANSWER = Since the p-value (0.0216) < α=0.05, we reject the null hypothesis H

2. Conduct a one-way ANOVA on the following data.

Group 1	4	9	10
Group 2	11	11	10
Group 3	1	6	4

What is your conclusion (use an alpha)? ANSWER= Reject H0

3. Given the following data:

	Variable B
Variable A	1	2	3
1	5	4	4
	2	6	9
	1	3	7
	4	1	5
	2	3	4
2	6	6	5
	2	7	7
	3	4	5
	3	3	4
	2	3	8

A) What is the value of F crit for the column effect (variable b ) *Hint: don't forget to evaluate a numerator (for variable B and denominator df within) ANSWER = 3.40

B) Given the following data, what is the value of the SS total? ANSWER = 121.8667
