They are also classified according to highest educational degree earned ("no college degree", "two-year degree", "four-year degree", or "advanced degree"). The results are given in the contingency table below.what is the relative frequency of people in the sample who do not have a college degree?round your answer to two decimal places.

Answer 1

Given:

Total people = 346

Find-: Relative frequency of people in the sample who do not have a college degree.

Sol:

Relative frequency is defined as:

`\text{ Relative frequency=}\frac{\text{ Subgroup frequency }}{\text{ Total frequency }}`

Total frequency = 346

Subgroup frequency is:

`\begin{gathered} =15+50+39 \\ \\ =104 \end{gathered}`

`\begin{gathered} =(104)/(346) \\ \\ =0.301 \end{gathered}`

The relative frequency is 0.301
