Question
a-2. Use a a = 0.05 level of significance, find or compute the critical value of F. (Round your answer to 2 decimal places.) The critical value of F is b. Using the ttest from Chapter 11, compute t. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.) c. There is any difference in the mean test scores. Ho. There is in the mean scores between lecture and distance-based formats.

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, t = 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 six students who took the course in the normal lecture format. The other group of eight 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 Lecture Distance 32 47 31 32 40 44 31 31 34 43 37 34 46 43 picture Click here for the Excel Data File. a-1.
