What test is used to get the p-value? Is the p-value
two-tailed or one-tailed? What is the sample size?
1. Figure 1A: Compare the QRS interval before exercise and after
exercise in athletes.
Figure 1B: Compare the QRS interval before exercise and
after exercise in non-athletes
2. Figure 2A: Compare the TP interval before exercise and
after exercise in athletes.
Figure 2B: Compare the TP interval before exercise
and after exercise in non-athletes.
3. Figure 3: Compare the heart rate before and after
exercise for all data (both groups combined).
4. Figure 4: Compare the mean resting heart rate in
athletes and non-athletes.
