what is the relative frequency of respondents who are democrat?
round your answer to two decimal places.

Explanation:

Sum the total number of Democrat respondents

Using the Descriptive Statistics knowledge point

$$ \text{Total Democrats} = 25 + 34 + 33 = 92 $$

Calculate the relative frequency of Democrats

Using the Descriptive Statistics knowledge point

$$ \text{Relative Frequency} = \frac{\text{Total Democrats}}{\text{Total Sample Size}} = \frac{92}{291} \approx 0.31615 $$

Round the result to two decimal places

Using the Descriptive Statistics knowledge point

$$ \text{Relative Frequency} \approx 0.32 $$
