A researcher wishes to determine if the college students with a
“B” average have attain more flying hours by the end of their first
semester of college than those that do not have a “B” average at
the end of the first semester. The researcher surveys 20 college
students that are also student pilots and records their flight
hours as well as their GPA (noted as “below B” and “B or better”),
and, fortunately, there is an equal number “below B” and “B or
better.” The expectation is that those students with a B average or
better will have more flying hours by the end of their first
semester than those students that are below a “B” average. Here are
the survey results:

Conduct a t test using the five-step hypothesis testing process
and StatCrunch. Show your work. (no hand writing)
1. Restate the question as a research hypothesis about the
population
2. Determine the comparison distribution
3. Determine the cutoff score where the null hypothesis will be
rejected
4. Determine your sample's score on the comparison
distribution
5. Decide whether to reject the null hypothesis
