1. Based on the following reported results, which study used the most subjects?

A)z = 1.29, n = 21

B)F(3, 16) = 3.16

C)Dependent t(19) = 2.17

D)Independent t(20) = 4.57

2.If MS_within is 6.08 and MS_between is 15.53, what is your F value?( Round to 2 decimal places)

3.Manny developed a study looking at the effect of diet on concentration. In the experiment, 86 subjects were placed on 6 possible diets.

Use the following table to determine whether diet influenced concentration Be sure to fill in the table correctly to get the conclusion!

Source	Sum of Squares	df	Mean Sum of Squares	F
Between groups	1478.3	???	???	???
Within groups	6675.20	???	???
Total	8153.2

A)Diet has a significant effect on Concentration at the p < 0.01 level only

B)Diet does not have a significant effect on Concentration at either the p < 0.05 or p< 0.01 levels

C)Diet has a significant effect on Concentration at the p < 0.05 and p < 0.01 levels

D)There is not enough information to determine the effect.

E)Diet has a significant effect on Concentration at the p < 0.05 level only

4. When interpreting F (14, 26) = 8.80, p < 0.05, how many groups were examined?
