To calculate the relative frequency, we need to divide the number of people who prefer island vacations and also prefer swimming by the total number of people who prefer island vacations.
The number of people who prefer island vacations and also prefer swimming is 40.
The total number of people who prefer island vacations is 12 + 40 = 52.
Relative frequency = 40 / 52 = 0.7692
Converting this to a percentage, we get:
0.7692 * 100 = 76.92%
So, the relative frequency that people who prefer island vacations also prefer swimming is 76.9%.
Use the table to answer the question.
Preferences | Mountains | Seaside | Island
Hiking | 45 | 20 | 12
Swimming | 12 | 53 | 40
Given the data in the table, what is the relative frequency that people who prefer island vacations also prefer swimming? Round the percentage to the nearest tenth.
