A human factors psychologist investigates which of two simulators (P and Q) results in improved task performance. Eight participants are randomly assigned to one of the two simulators and each participant's performance score is measured across five trials.

The performance scores are given below (normally far more cases would be used in an actual study).
(a) Compute the appropriate variance estimates; complete the F tests at and draw statistical conclusions. Show your results in a summary analysis of variance table
(b) Construct a graph of the cell means. Draw final conclusions.
