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 calculate the relative frequency, we need to divide the number of people age 12-15 who had over 500 text messages by the total number of people age 12-15.

The total number of people age 12-15 is 600.
The number of people age 12-15 who had over 500 text messages is 56.

To calculate the relative frequency, we divide 56 by 600, and then multiply by 100 to express it as a percentage:

Relative frequency = (56/600) * 100 = 9.3%

Therefore, the relative frequency of people age 12-15 who had over 500 text messages is 9.3%.
