Quizplus · Accepted Answer

The computed value of F is found by dividing the between-groups mean square by the within-groups mean square. In this case, the between-groups mean square is 162.5 and the within-groups mean square is 20.67. Therefore, the computed value of F is 7.84, which corresponds to choice B.
