Use the table to answer the question.
Number of Text Messages
Age 0–200 201–500 Over 500
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.
(1 point)
To find the relative frequency of people age 12-15 who had over 500 messages, we first need to add up the total number of people in that age group:
24 (0-200) + 47 (201-500) + 78 (over 500) = 149 people age 12-15
Then, we find the relative frequency by dividing the number of people in that age group who had over 500 messages by the total number of people in that age group:
78 / 149 = 0.5235
Rounded to the nearest tenth, the relative frequency is 52.4%.
