1. Is Jones correct? That is, using the more complete data set, is it true that Jones has the lowest defect rate overall? Are Jones’s percentages correct overall (i.e., combining domestic and overseas production)?
2. Is Wallace correct? That is, what percent of Wallace’s production was the more demanding? How does this compare to the other two managers? (Note: you may wish to compare conditional probabilities, given the manager, combining defective and non-defective production)
3. Look carefully at conditional defect rates given various combinations of manager and production client. What do you find?
4. Should you recommend that Wallace start looking for another job? If not, what do you suggest?
