Answer:
Relative frequency is 7.41% or 0.0741
Step-by-step explanation:
Given
The Attached Table
Required
Calculate the relative frequency of the class with lower limit 27
Relative Frequency is calculated by dividing individual frequency by the total frequency
Mathematically,

The total frequency of the given data is 6+8+4+2+5+2

The class with lower limit 27 has a frequency of 2;
Hence;
becomes


(Approximated)
You may also leave your answer in percentage form


Hence, the relative frequency is 7.41% or 0.0741
First of all, 15 minutes is 1/4 of an hour. So 8:15 is 8.25 hours.
