    Answer:

    B.) 75

    Step-by-step explanation:

    Given the following :

    median = 120

    Q1 = 100

    Q3 = 150

    minimum = 20

    maximum = 270

    Maximum length of a whisker =?

    The interquartile range (IQR) multiplied by 1.5

    The Interquartile range (IQR) :

    UPPER QUARTILE (Q3) – LOWER QUARTILE (Q1)

    150 – 100 = 50

    MAXIMUM WHISKER LENGTH :

    1.5 * INTERQUARTILE RANGE

    1.5 * IQR

    1.5 * 50

    = 75
