To find the relative frequency of the people age 12-15 who had over 500 messages, we first need to find the total number of people in this age group.
Total number of people age 12-15 = 24 + 47 + 78 = 149
Now, we need to find the number of people age 12-15 who had over 500 messages.
Number of people age 12-15 who had over 500 messages = 78
Relative frequency = (Number of people age 12-15 who had over 500 messages / Total number of people age 12-15) * 100
Relative frequency = (78 / 149) * 100 = 52.3%
Therefore, the relative frequency of the people age 12-15 who had over 500 messages is approximately 52.3%.

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
