Suppose we want to know whether or not three different exam prep programs lead to different mean scores on a certain exam. To test this, we recruit 30 students to participate in a study and split them into three groups, resulting in a balanced design. The students in each group are randomly assigned to use one of the three exam prep programs for the next three weeks to prepare for an exam.

Suppose we want to know whether or not three different exam
prep programs lead to different mean scores on a certain exam.
To test this, we recruit 30 students to participate in a study and
split them into three groups, resulting in a balanced design.
The students in each group are randomly assigned to use one of
the three exam prep programs for the next three weeks to
prepare for an exam. At the end of the three weeks, all of the
students take the same exam.
The exam scores statistics for each group are shown below:
Group 1 Group 2 Group 3
84.7
Average Exam Score 83.4 89.3
Exam Score Variance 71.1556 23.1222 28.0111
At the 0.05 level of significance, the conclusion is
