This is on a practice exam and I'm not sure how to work through the steps.

A professor of stats want to test four instructional methods for teaching stats. Students who signed up for the course are assigned at random to 4 sections: Section 1- Online, II- lectures, III- Independent study, and IV- Combination. Students in all four sections have to take a final exam. The scores range from 1 to 15

Section n xbar s squared

I 5 13.8 .7

II 5 13.2 2.2

III 5 11.2 2.7

IV 5 14.6 .3

a) Produce an analysis of variance table for the data

b) Test the hypothesis that the population means of scores are the same for the four instructional methods for teaching stats. Use alpha .01
