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
- 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:
Below B flying hours B or Better flying hours 43 52 41 32 31 44 36 58 39 51 37 30 36 44 41 55 45 62 41 52
