Given the data in the table about the number of text messages per day, what is the relative frequency of the people age 12-1 who had over 500 messages? Round the percentage to the nearest tenth.
First, let's calculate the total number of people in the age group 12-18 who had over 500 text messages:
5 + 8 + 3 + 2 = 18
Next, let's calculate the relative frequency of people age 12-18 who had over 500 text messages:
(18 / 100) * 100 = 18%
Therefore, the relative frequency of people age 12-18 who had over 500 text messages is 18%.
