A physiologist wants to determine whether a particular running program has an effect on resting heart rate. The heart rates of 15 randomly selected people were measured. The people were then put on the running program and measured again one year later. Thus, the before and after measurements for each person are a pair of observations.
You can use this data to demonstrate Paired t.
|Before||The resting heart rate of the person before the running program|
|After||The resting heart rate of the person after the running program|
|Difference||The difference between the person's resting heart rate before and after the running program|
