    Relative frequency of the (35 - 38) class = 0.2 = 20.0%

    Step-by-step explanation:

    Relative frequency is a measure of comparing a variable's frequency with the total/cumulative frequency.

    Mathematically, it is given as

    Relative frequency = (frequency of variable) / (total or cumulative frequency)

    Ages Number of students

    23-26 8

    27-30 2

    31-34 10

    35-38 6

    To find the relative frequency for the class with lower class limit 35

    From the table,

    The frequency of the (35 - 38) class = 6

    Total or cumulative frequency = sum of all the frequencies in the table = 2+2+8+2+10+6 = 30

    Relative frequency of the (35 - 38) class = 6/30 = 0.2 = 20.0%
