Answer
$53\%$ respondents answered 'Always'.
Work Step by Step
To find the percentage of respondents answering 'Always', we divide the number of 'Always' responses by the total number of responses (which is the relative frequency of the 'Always' response) and multiply it by $100\%$.
$$\frac{2518}{4776}\times100\%\approx53\%$$
So $53\%$ respondents answered 'Always'.
