multiple choice 1 point
32% 20% 34% 34%

Explanation:

Step1: Recall percentage formula

The formula to find the percentage of a part to the whole is $\text{Percentage}=\frac{\text{Part}}{\text{Whole}}\times100\%$. Here, the number of people who prefer biking is the part ($211$), and the total number of responses is the whole ($627$).

Step2: Calculate the percentage

$\text{Percentage}=\frac{211}{627}\times 100\%$. First, $\frac{211}{627}\approx0.3365$. Then, $0.3365\times100\% = 33.65\%\approx34\%$.

Answer:

34%
