Answer 2

Answer:

23.5−28.5,28.5−33.5,33.5−38.5,38.5−43.5,43.5−48.5,48.5−53.5

Step-by-step explanation:

Here,

Class size = Difference b/w any two consecutive class marks = 31-26 = 5

Therefore,

Lower limit of first class interval = 26 - 5/2 = 23.5

Upper limit of first class interval = 26 + 5/2 = 28.5

Therefore, first class interval is 23.5-28.5.

Thus, the class intervals are :

23.5−28.5,28.5−33.5,33.5−38.5,38.5−43.5,43.5−48.5,48.5−53.5
