Answer:

20-30

Lower limit:20

Upper limit:30

Class Size: 30-20= 10

30-40

Lower limit: 30

Upper limit :40

Class size: 40-30=10

40-50

Lower limit:40

Step-by-step explanation:

Upper limit refers to the higher value of the class interval.

Lower limit refers to the lower value of the class interval.

The class size refers to the number of observations in a class interval. It is calculated by calculating the difference between lower limit and the upper limit.

Class Size= Upper limit - Lower limit
