    A 238.5 Correct Answer Incorrect Answer
    B 271.25 Correct Answer Incorrect Answer
    C 314.75 Correct Answer Incorrect Answer
    D 284.55 Correct Answer Incorrect Answer

    Solution

    Total production (in thousands):
    A = 840 + 900 + 760 + 800 = 3300
    B = 680 + 750 + 620 + 540 = 2590
    C = 890 + 960 + 1000 + 1200 = 4050 Average: A = 3300 / 4 = 825, B = 2590 / 4 = 647.5 & C = 4050 / 4 = 1012.5 Combined average of A and C = (825 + 1012.5)/2 = 1837.5/2 = 918.75 Difference = 918.75 − 647.5 = 271.25
