1.A study reported in the Journal of the American Medical Association investigated the cardiac demands of heavy snow shoveling. Eight 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 eight subjects. At the .05 level of significance, test for any significant differences. Use both p-Value and Critical-Value approaches.
