The ANOVA summary table for the Exercise 3 data is presented below. Refer to this information and to the Exercise 3 information to answer the questions. Evaluate statistical significance with alpha equal to .05. Note that p-values are included in the summary table.

1. Is the picture color main effect statistically significant? If so, which color was associated with better memory test performance?

2. Is the cognitive style main effective statistically significant? If so, which cognitive style was associated with better memory test performance?
3. Is the interaction statistically significant? If so, which picture color is associated with better test performance for each of the two cognitive styles?

4. Calculate the proportion of variance explained by cognitive style.

5. Calculate the proportion of variance explained by the interaction.
