Answer 2

Hiking. 45.9%

Explanation:

According to the given table, the sport most preferred by people ages 20-29 is Hike with 123 people, the second most preferred by them was Swim with 88 people.

The relative frequency is a ratio between the absolute frequency and the total. In this case, the abosulte frequency is 123 and the total is 268, that is, 123 people out of 268 people between ages 20-29.

`F_(r)=(123)/(268) \approx 0.459`

Which is equvalen to 45.9%.

Therefore, the right answer is C.
