    Answer: A) 82.3

    Step-by-step explanation:

    Mean= average

    To find mean, you add up all the numbers and divide by the number of numbers.

    In this case you do:

    (81+78+83+89+80+87+78) ÷ 7

    81+78+83+89+80+87+78

    =576

    Now, divided by 7

    576 ÷ 7

    = 82.2857142857

    Round to nearest tenths place

    = 82.3
