Keisha performs an experiment with two randomly assigned groups of school children. The first group is allowed 15 minutes of recess play before a math test, while the second group watches a video before the test. When she analyzes the test scores, she finds that there is a statistical difference between the groups, with the recess group scoring higher on average. Which conclusions can be drawn from this result?
a. The difference between the scores for the two groups is probably due to random chance.
b. The difference between the scores for the two groups is likely due to their differing pretest activities, and did not happen by chance.
c. Students who are good at math prefer recess to watching a video.
d. Students who are good at math prefer watching a video to recess.
