Employees at a company produced refrigerators on three shifts.
Each shift recorded their quality stats below. A unit was
considered defective if it at least one part was assembled wrong or
was missing. Management believes that quality depends on the the
shift it was produced. Test the claim that shifts are independent
of quality using chi-square at alpha = 0.05. SHOW YOUR WORK
