    We first need to list the following Data Set:

    111, 133, 134, 183, 284, 334, 339

    Range = highest value - lowest value =

    Range = 339 - 111 = 228

    Interquartile range = upper quartile - lower quartile =

    (or IQR = interquartile range, another term)

    Interquartile range = 334 - 133 = 201

    It's B.

    Step-by-step explanation:

    The range is 344 - 111

    = 233.

    Arranging the data in ascending order:

    111 133 134 183 284 339 344

    The lower quartile = 133 and the upper quartile = 339.

    So the interquartile range = 339 - 133

    = 206.
