| 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 text messages, we first need to calculate the total number of people in that age group who had over 500 messages.
From the table, we see that the number of people age 12-15 with over 500 messages is 78.
Next, we need to find the total number of people in all age groups who had over 500 messages.
Total number of people with over 500 messages = 78 (age 12-15) + 97 (age 16-19) + 177 (age 20-23) = 352
Now, we can calculate the relative frequency for people age 12-15 who had over 500 messages:
Relative Frequency = (Number of people age 12-15 with over 500 messages) / (Total number of people with over 500 messages) * 100
Relative Frequency = (78 / 352) * 100
Relative Frequency = 0.2216 * 100
Relative Frequency ≈ 22.2%
Therefore, the relative frequency of people age 12-15 who had over 500 text messages is approximately 22.2%.
