    Step-by-step explanation:

    Range is calculated by the highest value in a given data set - lowest value

    Given the data set above, the highest value is 15, while the lowest value is 2

    To calculate range, we insert the values into the formula:

    Range = 15 - 2 = 13

    2) To calculate mean, we sum the total of all values in the data set and divide by the number of values

    Mean = 2 + 10 + 15 + 3+12+7+13+6+3+10/10

    = 83/10 = 8.3
