1. We are asked to find 2 statements that best fill in the blanks.

2. They must be comparable in expected speed based on the hypothesis. "The coach hypothesizes that the wind, and not the type of shoes worn, was responsible for the difference in speed." In other words, the wind affects the speed while shoes don't. It is also unknown the effect of where they ran. Based on this and the reports, an increase in wind speed gives a negative relationship with the expected speed.

3. For the two statements to fit, they need to both talk about the wind speed. We are left with:

- running on the school track and wind < 3 m/s
- wearing running shoes and wind < 3 m/s
- wearing running shoes and wind ≥ 3 m/s

4. The statement "running on the school track and wind < 3 m/s" can't be compared with the others because the effect of where they are running is unknown.

5. Using the hypothesis, we arrive with the answer: The hypothesis indicates that the coach would expect speeds associated with reports of wearing running shoes and wind ≥ 3 m/s to be less than speeds associated with reports of wearing running shoes and wind < 3 m/s.
