Use the table to answer the question.
Number of Text Messages
0–200 201–500 Over 500
Age 12–15 24 47 78
16–19 20 35 97
20–23 55 67 177
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.
____%
To find the relative frequency of people age 12-15 who had over 500 messages, we first need to find the total number of people in that age group:
Total number of people age 12-15 = 24 + 47 + 78 = 149
Next, we need to find the number of people age 12-15 who had over 500 messages, which is 78.
The relative frequency is calculated as:
Relative frequency = (Number of people with over 500 messages in age group 12-15) / (Total number of people in age group 12-15) * 100
Relative frequency = 78 / 149 * 100
Relative frequency ≈ 52.3%
Therefore, the relative frequency of people age 12-15 who had over 500 messages is approximately 52.3%.

Cherries Grapes
North 120 125
South 25 75
Examine the data from a survey about the part of the state people are from and the fruit they prefer. If a person prefers cherries, what is the percentage chance that they are from the North? Round your answer to the nearest tenth.
____%
To find the percentage chance that a person who prefers cherries is from the North, we first need to find the total number of people who prefer cherries:
Total number of people who prefer cherries = 120 (North) + 25 (South) = 145
Next, we need to find the number of people who prefer cherries and are from the North, which is 120.
The percentage chance is calculated as:
Percentage chance = (Number of people who prefer cherries from the North) / (Total number of people who prefer cherries) * 100
Percentage chance = 120 / 145 * 100
Percentage chance ≈ 82.8%
Therefore, the percentage chance that a person who prefers cherries is from the North is approximately 82.8%.
