Question

Chris asked his personal trainer if running on a treadmill was actually effective for losing weight. His trainer showed him some research that investigated the relationship between time spent running on the treadmill and number of calories burned. That researcher had already calculated the Sum of Products of Deviations and the SS for each variable. They are listed below.

SP = 18, SSx = 10, SSy = 40

Use the numbers above to calculate the Pearson correlation coefficient:

Is this a weak, moderate, or strong correlation?

What happens to the number of calories burned as the amount of time spent running on the treadmill increases?
