  1. 4.3
  2. 3.6
  3. 3.8
  4. 4

The correct answer is: 3.6


    text  Mean  end text equals fraction numerator 45 plus 50 plus 42 plus 38 plus 40 over denominator 5 end fraction equals 215 over 5 equals 43.
    text  deviation  end text equals plus 2 comma 7 comma negative 1 comma negative 5 comma negative 3
    M A D equals fraction numerator vertical line plus 2 vertical line plus 7 plus vertical line minus 1 vertical line plus vertical line minus 5 times vertical line plus vertical line minus 3 vertical line over denominator 5 end fraction equals 18 over 5 equals 3 times 6
