Question

Determine the relative frequency for the third class as a simplified fraction

Answer 1

GIVEN:

We are given a frequency distribution table showing different classes of hours of study and the frequency of each class of data.

Required;

To determine the relative frequency for the third class

Step-by-step solution;

For a relative frequyency, we need to find the number of times an event occurs and express it as a fraction of the total events that occured in the survey/experiment.

The events in this case are hours of study and the occurrence is the total frequency for all classes of hours of study.

The total frequency is;

$3+10+6+15+6=40$

The relative frequency for the third class therefore would be;

$\begin{gathered} Relative\text{ }Frequency_3=\frac{6}{40} \\ \\ Relative\text{ }Frequency=\frac{3}{20} \end{gathered}$

ANSWER:

The relative frequency of the third class therefore is

$\frac{3}{20}$
