Answer 1

Relative frequency = Number of people age 12-15 with over 500 messages / Total number of people age 12-15

Relative frequency = 78 / (24 + 47 + 78) = 78 / 149

Relative frequency ≈ 52.3%

Therefore, the relative frequency of people age 12–15 who had over 500 messages is approximately 52.3%.
