Assignment Help:
Eight students conducted a controlled experiment to demonstrate how walking and running
affected their heart rates. Use the data below to answer the following questions.
Effects of Activity on Heart Rate (in beats per minute)
Student Heart Rate
(at rest)
Heart Rate
(walking)
Heart Rate
(running)
1 70 90 115
2 72 80 100
3 80 100 120
4 65 75 95
5 88 112 125
6 74 83 104
7 75 88 109
8 77 95 130
8. The students came to the conclusion that heart rates rise by 10 to 20 beats per minute after
walking and 20 to 40 beats per minute after running. First, identify the independent (manipulating)
and dependent (responding) variables. Then, explain whether or not the data table supports this
conclusion.
