Given the table that shows the number of movies and the corresponding frequency, you can determine that the total frequency is:
[tex]Total\text{ }Frequency=25[/tex]
By definition:
[tex]Relative\text{ }Frequency=\frac{Frequency}{Total\text{ }Frequency}[/tex]
By definition, the Cumulative Frequency can be obtained by adding the corresponding frequency with the previous frequencies and dividing the sum by the Total Frequency.
Therefore, you can determine that:
- For:
[tex]Frequency=3[/tex]
You know:
[tex]Relative\text{ }Frequency=\frac{3}{25}[/tex]
And:
[tex]Cummulative\text{ }Relative\text{ }Frequency=\frac{3}{25}[/tex]
- Given:
[tex]Frequency=8[/tex]
You get:
[tex]Relative\text{ }Frequency=\frac{8}{25}[/tex]
And:
[tex]Cummulative\text{ }Relative\text{ }Frequency=\frac{3+8}{25}=\frac{11}{25}[/tex]
- Given:
[tex]Frequency=9[/tex]
You get:
[tex]Relative\text{ }Frequency=\frac{9}{25}[/tex]
And:
[tex]Cummulative\text{ }Relative\text{ }Frequency=\frac{3+8+9}{25}=\frac{4}{5}[/tex]
- Given:
[tex]Frequency=4[/tex]
You get:
[tex]Relative\text{ }Frequency=\frac{4}{25}[/tex]
And:
[tex]Cummulative\text{ }Relative\text{ }Frequency=\frac{3+8+9+4}{25}=\frac{24}{25}[/tex]
- Given:
[tex]Frequency=1[/tex]
You get:
[tex]Relative\text{ }Frequency=\frac{1}{25}[/tex]
And:
[tex]Cummulative\text{ }Relative\text{ }Frequency=\frac{3+8+9+4+1}{25}=\frac{25}{25}=1[/tex]
Hence, the answer is:
