Question: When only two treatments are involved, ANOVA and the Student’s t test (Chapter 11) result in the same conclusions. Also, for computed test statistics, t2 = F. To demonstrate this relationship, use the following example. Fourteen randomly selected students enrolled in a history course were divided into two groups, one consisting of 6 students who took the course in the normal lecture format. The other group of 8 students took the course as a distance course format. At the end of the course, each group was examined with a 50-item test. The following is a list of the number correct for each of the two groups.
Traditional Distance 32, 31, 40, 31, 34, 37
Lecture. 47, 32, 44, 31, 43, 34 46 43
a) complete the ANOVA table
a2) use a a=0.05 level of significance
b) using the t test from chapter 11 compute t
