To find the relative frequency, first calculate the total number of people who prefer island vacations:
12 (Hiking) + 40 (Swimming) = 52
Next, calculate the percentage of people who prefer swimming out of those who prefer island vacations:
40 (Swimming) / 52 (Total) * 100 = 76.9%
Therefore, the relative frequency that people who prefer island vacations also prefer swimming is 76.9%.
To find the relative frequency, first calculate the total number of people age 12-15 who had over 500 messages:
78 people in the 12-15 age group had over 500 messages.
Next, calculate the total number of people in the 12-15 age group:
24 (0-200) + 47 (201-500) + 78 (Over 500) = 149
Finally, calculate the percentage of people age 12-15 who had over 500 messages:
78 (Over 500) / 149 (Total) * 100 = 52.3%
Therefore, the relative frequency of people age 12–15 who had over 500 messages is 52.3%.
