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.

Answer 1

To find the relative frequency of the people age 12-15 who had over 500 text messages, we need to first calculate the total number of people in that age group and then divide the number of people who had over 500 messages by that total.

According to the table:
Total people age 12-15 = 500
Number of people age 12-15 who had over 500 messages = 40

Relative Frequency = (Number of people age 12-15 who had over 500 messages / Total people age 12-15) * 100
Relative Frequency = (40 / 500) * 100
Relative Frequency = 0.08 * 100
Relative Frequency = 8%

Therefore, the relative frequency of the people age 12-15 who had over 500 messages is 8%.
