The test statistic is 2.68 please help! If I get one more wrong it starts me over :(

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) Workout #1 Workout #2 Workout #3 Workout #4 164 154 184 155 174 155 182 162 159 159 193 167 177 174 189 175 157 182 167 190 Copy Data Step 2 of 2: Make the decision to reject or fail to reject the null hypothesis that equal average maximum heart rates are achieved by the four workouts and state the conclusion in terms of the original problem. Use a = 0.05. Answer Tables Keypad Keyboard Shortcuts O four workouts . We fail to reject the null hypothesis. There is not sufficient evidence, at the 0.05 level of significance, of a difference among the average maximum heart rates for the We reject the null hypothesis. There is sufficient evidence, at the 0.05 level of significance, of a difference among the average maximum heart rates for the four workouts. Submit
