- A researcher wishes to determine if a particular drug affects pilot reaction time to air traffic controller instructions. The researcher has 10 randomly chosen pilots. The pilots are observed in normal performance and their reaction times, in seconds, are recorded (Trial 1). Then the same pilots are administered the drug, observed again under the same exact conditions, and their reaction times are again recorded (Trial 2). The expectation is that the drug will reduce reaction time in all pilots. Test at an (significant level) of 0.05. Assume that the differences in these two samples are normally distributed and the population the data came from is normally distributed.
