To find the relative frequency of people who prefer swimming among those who prefer island vacations, we need to determine the number of people who prefer swimming to the total number of people who prefer island vacations.
From the table:
- People who prefer swimming at the island: 40
- People who prefer hiking at the island: 12
Now we can calculate the total number of people who prefer island vacations by adding those who prefer swimming and those who prefer hiking:
Total island preferences = 40 (swimming) + 12 (hiking) = 52
Next, we calculate the relative frequency of people who prefer swimming among the island vacationers:
Relative frequency = (Number of people who prefer swimming at the island) / (Total island preferences)
Relative frequency = 40 / 52
Now, we can convert this to a percentage:
Relative frequency as a percentage = (40/52) * 100 ≈ 76.9231%
Rounding to the nearest tenth, the relative frequency is approximately:
76.9%
