Use the table to answer the question. %C2%A0 Number of Text Messages %C2%A0 %C2%A0 0–200 201–500 Over 500 Age 12–15 24 47 78 16–19 20 35 97 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.
To find the relative frequency, we need to divide the number of people age 12-15 who had over 500 messages by the total number of people in that age group.
The total number of people age 12-15 is 24 + 47 + 78 = 149.
The number of people age 12-15 who had over 500 messages is 78.
To find the relative frequency, we divide 78 by 149 and multiply by 100 to convert to a percentage:
Relative frequency = (78 / 149) * 100 = 52.348993288590604
Rounded to the nearest tenth, the relative frequency is 52.3%.
Therefore, the relative frequency of the people age 12-15 who had over 500 messages is 52.3%.
