A physical trainer has four workouts that he recommends for his
clients. The workouts have been designed so that the average
maximum heart rate achieved is the same for each workout. To test
this design he randomly selects twenty people and randomly assigns
five of them to use each of the workouts. During each workout, he
measures the maximum heart rate in beats per minute with the
following results. Can the physical trainer conclude that there is
a difference among the average maximum heart rates which are
achieved during the four workouts? Maximum Heart Rates (Beats per
Minute)
Maximum Heart Rates (Beats per Minute)
Workout #1   Workout #2   Workout

151   187   185   173
154   194   186   177
156   156   179   161
156   176   190   161
177   163   167   156
Step 1 of 2:
Find the value of the test statistic to test for a difference
between the workouts. Round your answer to two decimal places, if
necessary.
