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. (1 point)
To find the relative frequency, we need to determine the total number of people in the age group 12-15 who had over 500 messages and then divide that by the total number of people in that age group.
Total number of people in the age group 12-15 who had over 500 messages = 78
Total number of people in the age group 12-15 = 24 + 47 + 78 = 149
Relative frequency = (78/149) * 100
Relative frequency = 0.5235 * 100
Relative frequency = 52.4%
Therefore, the relative frequency of people aged 12-15 who had over 500 messages is 52.4%.
