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 of people age 12-15 who had over 500 messages, we need to first calculate the total number of people in that age group and then determine how many of them had over 500 messages.
From the data provided, we know that there are a total of 24 people aged 12-15.
Out of those people, we see that only 1 person had over 500 messages.
Therefore, the relative frequency of people age 12-15 who had over 500 messages is 1/24 = 0.0417 or 4.2% when rounded to the nearest tenth.
