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
The relative frequency of people age 12-15 who had over 500 text messages per day can be calculated by dividing the frequency of people age 12-15 who had over 500 text messages by the total number of people age 12-15 in the sample:
Relative Frequency = Number of people age 12-15 who had over 500 messages / Total number of people age 12-15
Relative Frequency = 15 / 150 = 0.1
To convert this to a percentage, we multiply by 100:
Relative Frequency = 0.1 * 100 = 10%
Therefore, the relative frequency of people age 12-15 who had over 500 text messages per day is 10%.
