6	5
4	6
7	5
6	6
7	5
6	5

(A) Test whether or not mean ratings differ at a 0.05 level of significance. State the value of the test statistic. (Round your answer to three decimal places.) ___

(B) Compute effect size using eta-squared. (Round your answer to two decimal places.) ___

Answer 1

Answer 7A)

At 0.05 level of significance, there is not enough eviidence to reject the claim that mean ratings differ.

The value of the test statistic is 1.085

Answer 7B)

The formula for Eta squared is as follows:

Eta-squared = 1.085^2/(1.085^2+6-1)

Eta-squared = 0.19
