Question: Suppose we are interested in the effect of fatigue on task performance. Fourteen people are randomly assigned to either an experimental or a control group. The control group is tested immediately. The experimental group is tested after being deprived of sleep for 24 hours. The data are given here. Did fatigue affect performance? Give a full conclusion stating the alpha level, the finding, and the statistical string. (For an example of a statistical string, please look at step 7, in Box 10-2 on page 216. In that case the statistical string was “t(18) = 2.52, p < .05.”)
