The relative frequency of girls considered to be frequent texting will be 67.12%. And the relative frequency of boys considered to be frequent texting will be 59.09%.

What is a relative frequency?

Relative frequency, from the other end, is a technique of comparing the frequency of a certain event to the overall number of occurrences.

Three hundred middle school students were asked how many text messages they send each week.

Sending greater than 30 text messages is considered frequent texting.

Then the relative frequency of girls considered to be frequent texting will be

The total number of the girls will be

Total girls = 146

Then the relative frequency will be

$\rm RF = \dfrac{98}{146}\\\\RF = 0.6712 \ or \ 67.12\%$

The total number of the boys will be

Total girls = 154

Then the relative frequency will be

$\rm RF = \dfrac{91}{154}\\\\RF = 0.5909\ or \ 59.09\%$
