A researcher wished to compare the effect of the rate of stepping on heart rate during a step aerobics workout. Forty adult volunteers were randomly divided into four groups of 10 subjects each. Each group did a standard step aerobics workout: Group 1 at a low rate of stepping, Group 2 at a medium rate of stepping, Group 3 at a rapid rate, and Group 4 at rest. The mean heart rate at the end of the workout for all subjects was determined in beats per minute and presented at the table below. Assume the data for the three groups are independent and approximately Normal, =0.05. Calculate the degrees of freedom _ _, mean square of groups _ _ (Rounding to 3^rd decimal place), mean square of error _ _ (Rounding to 3^rd decimal place), statistics _ _ (Rounding to 3^rd decimal place), p-value _ _ (Rounding to 3^rd decimal place), and conclusion _ _. Which groups are significantly different from the control group? _ _.

Group 1: 94,84,89,89,93,86,95,100,102,78

Group 2: 99,104,90,102,97,107,103,93,101,106

Group 3: 115,113,116,123,109,119,121,129,133,108

Group 4: 63,73,84,86,84,79,86,68,73,82
