-Refer to Exhibit 13-5. The mean square within treatments (MSE) is
A)60 
B)15 
C)300 
D)20

Quizplus · Accepted Answer

The MSE is calculated by taking the sum of squared errors within each treatment group and dividing it by the degrees of freedom within the error term. From the table, we can see that the sum of squared errors within treatments is 240 and the degrees of freedom within error is 12, therefore MSE = 240/12 = 20. Therefore, the correct choice is D.
