Can you please check my work for a-c
When only two treatments are involved, ANOVA and the Student's f-test (Chapter 11) result in the same conclusions. Also, for computed test statistics, I = 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 in a distance 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 36 45 31 35 45 34 35 33 45 36 Expicture Click here for the Excel Data File. Required a-1.

(Round your answer to 2 decimal places.) The critical value of F is 0.52 b. Using the t-test from Chapter 11, compute z (Negative amount should be indicated by a minus sign.

There is no statistically significant difference in the mean scores between lecture and internet-based formatsStep by Step Solution
