A study reported in the Journal of the American Medical Association investigated the cardiac demands of heavy snow shoveling. Ten healthy men underwent exercise testing with a treadmill and a cycle ergometer modified for arm cranking. The men then cleared two tracts of heavy, wet snow by using a lightweight plastic snow shovel and an electric snow thrower. Each subject’s heart rate, blood pressure, oxygen uptake, and perceived exertion during snow removal were compared with the values obtained during treadmill and arm-crank ergometer testing. Suppose the following table gives the heart rates in beats per minute for each of the 10 subjects.

Question

A study reported in the Journal of the American Medical Association investigated the cardiac demands of heavy snow shoveling. Ten healthy men underwent exercise testing with a treadmill and a cycle ergometer modified for arm cranking. The men then cleared two tracts of heavy, wet snow by using a lightweight plastic snow shovel and an electric snow thrower. Each subject’s heart rate, blood pressure, oxygen uptake, and perceived exertion during snow removal were compared with the values obtained during treadmill and arm-crank ergometer testing. Suppose the following table gives the heart rates in beats per minute for each of the 10 subjects.

alpha = .05 

what is the p-value? 

The table presents data on the performance of ten subjects across four different physical activities: Treadmill, Arm-Crank Ergometer, Snow Shovel, and Snow Thrower. The values provided represent some measure of activity, perhaps heart rate, speed, or energy exertion, specific to each subject and activity.

| Subject | Treadmill | Arm-Crank Ergometer | Snow Shovel | Snow Thrower |
|---------|-----------|---------------------|-------------|--------------|
| 1       | 177       | 205                 | 180         | 98           |
| 2       | 151       | 177                 | 164         | 120          |
| 3       | 184       | 166                 | 167         | 111          |
| 4       | 161       | 152                 | 173         | 122          |
| 5       | 192       | 142                 | 179         | 151          |
| 6       | 193       | 172                 | 205         | 158          |
| 7       | 164       | 191                 | 156         | 117          |
| 8       | 207       | 170                 | 160         | 123          |
| 9       | 177       | 181                 | 175         | 127          |
| 10      | 174       | 154                 | 191         | 109          |

The table is structured with subjects listed in rows and the activities as column headers. The data highlights variations in performance measures for each activity per subject. For example, Subject 6 demonstrates high performance in the Snow Shovel activity with a value of 205, whereas Subject 5 shows a lower performance on the Arm-Crank Ergometer with a value of 142. This table can be used in educational contexts to analyze individual differences in performance across varied types of physical tasks.
