1.A researcher wishes to determine if a particular drug affects pilot reaction time to air traffic controller instructions. The researcher has 10 pilots. The pilots are observed in normal performance and their reaction times are recorded. Then the pilots are administered the drug, observed again, and their reaction times are recorded. The expectation is that the drug will reduce reaction time. Conduct a t test using the five-step hypothesis testing process. Show your work.

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." Conduct a t test using the five-step hypothesis testing process. Show your work. 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 62 52
