Answer:
Step-by-step explanation:
Class Size = Difference between consecutive class marks = 54 - 34
Class Size = 20
1st interval
Lower Class Boundary = 34 - 20/2 = 24
Higher Class Boundary = 34 + 20/2 = 44
2nd interval
Lower Class Boundary = 54 - 20/2 = 44
Higher Class Boundary = 54 + 20/2 = 64
So the class limit of 2 intervals are
1) 24, 44
2) 44, 65
