Air traffic controllers perform the vital function of regulating   the traffic of passenger planes. Frequently, air traffic controllers work   long hours with little sleep. Researchers wanted to test their ability to   make basic decisions as they become increasingly sleep deprived. To test   their abilities, a sample of 6 air traffic controllers is selected and given   a decision-making skills test following 12-hour, 24-hour, and 48-hour sleep   deprivation. Higher scores indicate better decision-making skills. The table   lists the hypothetical results of this study.   Sleep   Deprivation              12 Hours 24 Hours 48 Hours             23 17 16             18 21 20             34 23 21             27 20 14             23 15 16             20 21 14             (a) Complete   the F-table.

(Assume experiment-wise   alpha equal to 0.05. Select all that apply.)   There is a   significant difference in decision making for the 12-hour and 24-hour sleep   deprivation conditions.     There are no   significant differences between any of the groups.         There is a   significant difference in decision making for the 24-hour and 48-hour sleep   deprivation conditions.     There is a   significant difference in decision making for the 12-hour and 48-hour sleep   deprivation conditions.
