Use the table to answer the question.
Number of Text Messages
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 calculate the relative frequency, we need to first find the total number of people in the age group 12-15 who had over 500 text messages. From the table, we see that there were 78 people age 12-15 in total, and 47 who had between 201-500 messages and 78 who had over 500 messages.
Relative Frequency = Number of people with over 500 messages / Total number of people in age group 12-15
Relative Frequency = 78 / 78
Relative Frequency = 1
To convert this to a percentage, we multiply by 100:
Relative Frequency = 1 * 100 = 100%
Therefore, the relative frequency of people age 12-15 who had over 500 text messages is 100%.
