1) The following summary table presents the results from an ANOVA comparing three treatment conditions with n = 20 participants in each condition. Compute all missing values . (Hint: Start with the df column.) (3.5 points)

Source	SS	df	MS
Between Treats.			10	F =
Within Treats.
Total	176

2) One possible explanation for why some birds migrate and others maintain year-round residency in a single location is intelligence. Specifically, birds with small brains, relative to their body size, are simply not smart enough to find food during the winter and must migrate to warmer climates where food is easily available (Sol, Lefebvre, & Rodriguez-Teijeiro, 2005). Birds with bigger brains, on the other hand, are more creative and can find food even when the weather turns harsh. Following are hypothetical data similar to the actual research results. The numbers represent relative brain size for the individual birds in each sample.

Non-Migrating	Short-Distance Migrants	Long Distance Migrants
18	6	2	N = 18
13	11	7	G = 168
19	7	3	∑X2 = 2030
12	9	4
16	8	3
12	13	5
M1 = 15	M2 = 9	M3 = 4
T1 = 90	T2 = 54	T3 = 24
SS1 = 48	SS2 = 34	SS3 = 16

3) New research suggests that watching television, especially shoes about medical emergencies and hospitals, can result in increased concern about personal health, (Ye, 2010). Surveys administered to college students measure television viewing habits and health concerns such as fear of developing the diseases and disorders seen on television. For the following data, students are classified into three categories based on their television viewing patterns and health concerns are measured on a 10-point scale with 0 indicating “none.”

	Television Viewing
Little or None	Moderate	Substantial
4	5	5
2	7	8
5	3	7
1	4	6
3	7	8
7	6	10
4	2	6
4	6	4
8	3	6
2	5	8

Present a completed results table, the decision to be made, and report that decision in APA format . Use α = .05. (5.5 points)
