The track coach at a particular school had her student athletes practice running outside of scheduled training sessions and report details to her. She had them report speed as kilometers run divided by time running, whether they wore running shoes or other athletic shoes, whether they ran on the school track or not, and whether the wind was ≥ 3 meters per second (m/s) or < 3 m/s. She found that, overall, reports of greater than average speeds correlated with reports of both winds < 3 m/s and wearing running shoes. She also found that reports of less than average speeds correlated with reports of both winds ≥ 3 m/s and wearing shoes other than running shoes. The coach hypothesizes that the wind, and not the type of shoes worn, was responsible for the difference in speed.
The hypothesis indicates that the coach would expect speeds associated with reports of
1 to be less than speeds associated with reports of
