(1 point)
To find the relative frequency of people who prefer island vacations also prefer swimming, we need to calculate the joint frequency for island vacations and swimming, which is 40.
Then, we divide this joint frequency by the total number of people who prefer island vacations, which is 12 + 40 = 52.
Relative frequency = 40/52 ≈ 0.7692
Converting this to a percentage, we get 76.9%.
Therefore, the relative frequency that people who prefer island vacations also prefer swimming is 76.9%.

Given the data in the table about the number of text messages per day, what is the relative frequency of the people age 12–15 who had over 500 messages? Round the percentage to the nearest tenth.
(1 point)
To find the relative frequency of people age 12-15 who had over 500 messages, we need to look at the frequency in the table, which is 78.
Then, we need to calculate the total number of people age 12-15, which is the sum of the frequencies in the row for that age group: 24 + 47 + 78 = 149.
Relative frequency = 78/149 ≈ 0.5235
Converting this to a percentage, we get 52.4%.
Therefore, the relative frequency of people age 12-15 who had over 500 messages is 52.4%.
