An experiment was conducted to examine the effect of age on heart rate when subjects perform a specific amount of exercise. Ten male subjects were randomly selected from four age groups: 10–19, 20–39, 40–59, and 60–69. Each subject walked a treadmill at a fixed grade for a period of 12 minutes, and the increase in heart rate—the difference in rates before and after exercise— was recorded (in beats per minute). Preliminary calculations yielded Total SS = 1002.975 and SST = 67.475.
a Construct the associated ANOVA table.
b Do the data provide sufficient evidence to indicate differences in mean increase in heart rate among the four age groups? Test by using α = .05.
