Question: Read Example. Suppose that the purpose of the study was to determine whether pilots should be allowed to consume alcohol the evening prior to their flights, and that in this study the alcohol consumption occurred 12 hours before the measurement of the time of useful performance. Refer to the discussion of Type 1 and Type 2 errors.
a. Explain what the consequences of each type of error would be in this situation.
b. Which type of error would be more serious? Explain.
c. Given the data and results of the study, which type of error could have been made?
Example: Why Can't the Pilot Have a Drink? Ten pilots performed tasks at a simulated altitude of 25,000 feet. Each pilot performed the tasks in a completely sober condition and, three days later, after drinking alcohol. The response variable is the time (in seconds) of useful performance of the tasks for each condition. The longer a pilot spends on useful performance, the better.
