Answer:
Ages Number of students
15-18 2
19-22 4
23-26 8
27-30 9
31-34 6
35-38 3Based on the frequency distribution above, is 34 a :class width
lower class limit
upper class limit
class midpoint
2nd answer if you understand
We want to get the relative frequency for the class with a lower limit of 35, we will get that it is 20%.
How to get the relative frequency?
To get it we need to get the quotient between the number of people with a lower limit of 35 (are 6 of these) and the total number of students (2 + 2 + 8 + 2 + 10 + 6 = 30), times 100%.
So here the relative frequency is just:
RF = (6/30)*100% = 20%
Meaning that 20% of the students are in the range from 35 to 38.
