The relative frequency is the percentage of a count over the total count.
To get the relative frequency, here are the steps:
1. Get the total count.
[tex]\begin{gathered} N=4+8+20+74+336+212 \\ N=654 \end{gathered}[/tex]
2. Divide each frequency or count by 654.
For example, the frequency between 10 - 13.9 km/h is 4 players.
[tex]\begin{gathered} P=\frac{x}{N} \\ P=\frac{4}{654} \\ P=0.0061 \end{gathered}[/tex]
Hence, the relative frequency for the first class interval is 0.0061.
Moving on to the next interval 14 - 17.9 km/h. x = 8 players
[tex]P=\frac{x}{N}=\frac{8}{654}=0.0122[/tex]
Moving on to the next interval 18-21.9 km/h. x = 20 players
[tex]P=\frac{x}{N}=\frac{20}{654}=0.0306[/tex]
Moving on to the 4th interval 22 - 25.9 km/h . x = 74 players
[tex]P=\frac{x}{N}=\frac{74}{654}=0.1131[/tex]
At 5th interval 26 - 29.9 km/h, x = 336 players.
[tex]P=\frac{x}{N}=\frac{336}{654}=0.5138[/tex]
Finally, at the last interval 30 - 33.9 km/h, x = 212 players.
[tex]P=\frac{x}{N}=\frac{212}{654}=0.3242[/tex]
Completing the table, we have:
