Answer:
Class 3rd has the highest relative frequency and class 4th has the lowest relative frequency.
Step-by-step explanation:
To calculate class width we use the formula given below;
Class Width = <u>Maximum Value - Minimum Value </u>
Number of Classes
Class Width : = 2 approximately.
Relative frequency is obtained by counting each class frequency.
Class Frequency Relative Frequency
1 - 2 7 0.1944
3 - 4 8 0.2223
5 - 6 10 0.2778
7 - 8 4 0.1111
9 - 10 7 0.1944
Class 3rd has the highest relative frequency and class 4th has the lowest relative frequency.
