Question

If a relative frequency distribution is constructed for this data set, what is the relative frequency for the first class, 40-44?

Answer 1

From the question we are given the table below

From the table we are to find the relative frequency of the first class, 40 - 44

Relative frequency is defined as

From the table

Subgroup frequency = 7

Total frequency = 50

Therefore, for class 40 - 44

`R\text{elative frequency }=(7)/(50)=0.14`

Therefore, the relative frequency of the first class, 40 - 44 is 14%
