15. Suppose that we conduct a survey and ask a random sample of SBCC students to report their daily amount of exercise and report whether or not they have a dog. Suppose that we find the result to be significant: that there is a significant difference in the average minutes of daily exercise between the two groups. p-value = 0.003. There are three possible explanations:
- Having a dog causes students to get more exercise.
- Those who have a dog and those who do not have a dog have different amounts of daily exercise to begin with (groups differed at baseline)
- Random chance.
Can we rule out explanation #2?
