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
[tex]\operatorname{Re}lative\text{ frequency }=\frac{Subgroup\text{ frequency}}{Total\text{ frequency}}[/tex]
From the table
Subgroup frequency = 7
Total frequency = 50
Therefore, for class 40 - 44
[tex]R\text{elative frequency }=\frac{7}{50}=0.14[/tex]
Therefore, the relative frequency of the first class, 40 - 44 is 14%
