Answer:
The relative frequency in this category is 0.2
Step-by-step explanation:
The relative fraquency of a category is given by the number of observations in this category divided by the total number of observations.
In this question:
The category of interest has 15 observations.
In total, the population has 75 observations.
So the relative frequency is:
[tex]\frac{15}{75} = \frac{1}{5} = 0.2[/tex]
