Question

Twenty-five randomly selected students were asked the number of movies they watched the previous week. The results are as follows.

Answer 1

Given the table that shows the number of movies and the corresponding frequency, you can determine that the total frequency is:

`Total\text{ }Frequency=25`

By definition:

`Relative\text{ }Frequency=\frac{Frequency}{Total\text{ }Frequency}`

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:

`Frequency=3`

You know:

`Relative\text{ }Frequency=(3)/(25)`

And:

`Cummulative\text{ }Relative\text{ }Frequency=(3)/(25)`

- Given:

`Frequency=8`

You get:

`Relative\text{ }Frequency=(8)/(25)`

And:

`Cummulative\text{ }Relative\text{ }Frequency=(3+8)/(25)=(11)/(25)`

- Given:

`Frequency=9`

You get:

`Relative\text{ }Frequency=(9)/(25)`

And:

`Cummulative\text{ }Relative\text{ }Frequency=(3+8+9)/(25)=(4)/(5)`

- Given:

`Frequency=4`

You get:

`Relative\text{ }Frequency=(4)/(25)`

And:

`Cummulative\text{ }Relative\text{ }Frequency=(3+8+9+4)/(25)=(24)/(25)`

- Given:

`Frequency=1`

You get:

`Relative\text{ }Frequency=(1)/(25)`

And:

`Cummulative\text{ }Relative\text{ }Frequency=(3+8+9+4+1)/(25)=(25)/(25)=1`

Hence, the answer is:
