    Answer:

    9

    Step-by-step explanation:

    Arrange data set

    19, 4, 17, 3, 6, 5,5, 3, 11, 12, 3, 7, 15, 8, 8, 10,5, 3, 12, 41, 36

    in ascending order

    3, 3, 3, 3, 4, 5, 5, 5, 6, 7, 8, 8, 10, 11, 12, 12, 15, 17, 19, 36, 41

    The median is Q_2=8

    Q_1=\dfrac{4+5}{2}=4.5  

    Q_3=\dfrac{12+15}{2}=13.5

    Thus, the interquartile range is

    Q_3-Q_1=13.5-4.5=9
