Question

The two-way frequency table represents data from a survey asking a random sampling of people whether they can see the sunrise or sunset from the front of their home. A 4-column table with 3 rows. The first column has no label with entries sunset, no sunset, total. The second column is labeled sunrise with entries 14, 7, 21. The third column is labeled no sunrise with entries 12, 5, 17. The fourth column is labeled total with entries 26, 12, 38. Which is the joint relative frequency for the people who can only see the sunset? StartFraction 5 Over 38 EndFraction StartFraction 7 Over 38 EndFraction StartFraction 12 Over 38 EndFraction StartFraction 14 Over 38 EndFraction.

Answer 1

You can use the fact that joint relative frequency is the ratio of the frequency of the certain category to the total frequency of that category.

The joint relative frequency for the people who can only see the sunset is given by

Option C: $\dfrac{12}{38}$

How to calculate the joint relative frequency?

Suppose you've to calculate the joint relative frequency of a certain category out of the given big category.

Then its the ratio of the frequency of that certain category to the total frequency of that big category.

See below for more clarity.

Using the definition of joint relative frequency to find the needed frequency

The given table is attached below in diagram.

The needed joint relative frequency for the people who can only see the sunset is given by

$\dfrac{\text{Total people who can view only sunset}}{\text{total number of people in the given context}} = \dfrac{12}{38}$

Thus,

The joint relative frequency for the people who can only see the sunset is given by

Option C: $\dfrac{12}{38}$
