    The correct answer is option "C"

    "The interquartile range increases"

    The value of the (RIC) will increase from 4 to 5.75, that is, 44%

    Step-by-step explanation:

    The range is defined as the difference between the maximum and minimum value of a series of data. Xmax - Xmin

    The interleaving range (RIC) is a measure of dispersion that measures the central range of 50% of the data.

    Therefore, if a low value is included, such as five, the variance of the data would be greater and, consequently, the value of the (RIC) will increase from 4 to 5.75, that is, 44%
