[1.5%] ANOVA: Three groups of 5 students were tested in their ability to correctly answer a 10question quiz under different formats. Group 1 had a True/False quiz, Group 2 had a FillIn quiz, and Group 3 had a Multiple Choice quiz. Their scores were as follows:
True/False FillIn Multiple Choice
6 3 6
8 5 10
9 6 6
7 7 8
10 5 7
Test whether there was a difference in performance on answering the same general questions under different formats. Use a .05 level of significance.
6a) Pvalue = ________________
6b) REJECT THE NULL or DO NOT REJECT THE NULL? (circle one)
