For the following questions: Please ensure that all numeric answers are rounded to two decimal points, unless the number is already an integer or has only one decimal point. In these cases, do not add additional decimal points. A study is conducted to evaluate the effect of two different teaching methods (Method A and Method B) and two levels of class duration (30 minutes vs. 60 minutes) on the test scores of students. The study involves a completely randomized design with four groups, each containing five students. Data Set: 30 minutes 60 minutes Method A 65, 70, 68, 66, 69 84, 82, 87, 85, 83 Method B 50, 55, 53, 51, 54 75, 77, 76, 74, 78 a. Calculate the Sum of Squares for 1) Factor A (teaching methods), 2) Factor B (class duration), 3) The interaction between Factors A and B, and 4) The error (SSE). b. Compute the Mean Square for 5) Factor A, 6) Factor B, 7) the interaction, and 8) the error (MSE). d. Calculate the F-ratios for 9) Factor A, 10) Factor B, and 11) the interaction.
