To find the relative frequency of people who prefer island vacations also prefer swimming, we need to divide the number of people who prefer island vacations and swimming by the total number of people who prefer island vacations.
Total number of people who prefer island vacations = 12 + 40 = 52
Number of people who prefer island vacations and swimming = 40
Relative frequency = (40 / 52) * 100% = 76.9%
Therefore, the relative frequency that people who prefer island vacations also prefer swimming is 76.9%.
To find the relative frequency of people age 12-15 who had over 500 text messages, we need to divide the number of people age 12-15 who had over 500 text messages by the total number of people age 12-15.
The total number of people age 12-15 = 24 + 47 + 78 = 149
Number of people age 12-15 who had over 500 messages = 78
Relative frequency = (78 / 149) * 100% = 52.3%
Therefore, the relative frequency of people age 12-15 who had over 500 messages is 52.3%.
To find the percentage chance that a person who prefers cherries is from the North, we need to divide the number of people from the North who prefer cherries by the total number of people who prefer cherries.
Total number of people who prefer cherries = 120 + 25 = 145
Number of people from the North who prefer cherries = 120
Percentage chance = (120 / 145) * 100% ≈ 82.8%
Therefore, the percentage chance that a person who prefers cherries is from the North is approximately 82.8%.
