    Answer:

    3.9

    Step-by-step explanation:

    Mean: 15 + 13 + 9 + 3 + 10 + 5 + 3 + 1 + 7 = 66/9 = 7.3

    7.3 – 15 = 7.7

    7.3 – 13 = 5.7

    7.3 – 9 = 1.7

    7.3 – 3 = 4.3

    7.3 – 10 = 2.7

    7.3 – 5 = 2.3

    7.3 – 3 = 4.3

    7.3 – 1 = 6.3

    7.3 – 7 = 0.3

    7.7 + 5.7 + 1.7 + 4.3 + 2.7 + 2.3 + 4.3 + 6.3 + 0.3 = 35.3/9 = 3.9
