Answer:
18.4%
Step-by-step explanation:
The formula for rel. freq. is:
Relative Frequency = Class Frequency/n
Where
Class Frequency will be the number of students in the class we are interested in (in 35-38, the number of students is 9)
n is the total number of students [which is 6+7+8+9+10+9= 49]
Putting into formula we get:
Relative Frequency = 9/49 = 0.1837
To get percentage, we need to multiply by 100:
0.1837 * 100 = 18.37%
Rounded to 1 decimal place, that is 18.4%
