    3.5

    Step-by-step explanation:

    Find the Mean of the Population Data Set

    4 + 6 + 7 + 11 + 12 + 18 + 26 + 23 + 14 + 31 + 22 + 12 = 186

    186 : 12 = 15.5

    Find the Mean of the Sample Data Set

    11 + 31 + 22 + 12 = 76

    76 : 4 = 19

    Subtract

    19 - 15.5 = 3.5

    Answer: The sample mean is more than the population mean by 3.5
