(d) Test the hypothesis that the increase in the speed of 1 km/h results in the runner's heart rate average increase of 7 points at
a = 0.05. Suppose that the alternative hypothesis is that the average increase of the runner's heart rate in this situation does not
equal 7 points.
There is
evidence to conclude that the increase in the speed of 1 km/h does not result in the runner's heart rate
average increase of 7 points at a = 0.05.
