    I would go with C only because you have the find the median of the lower half of the data set This means that about 25% of the numbers in the data set lie below Q1 and about 75% lie above Q1.

    Step-by-step explanation:

    Lower quartile (xL) : 26.5

    Median (xm) : 37

    Upper quartile (xU) : 44.5
