Answer 2

Hey mate
Here is your answer :--

1) modal class is 74.5-79.5 because it has the maximum frequency

2) median class :-
class nearest to N/2
200/2= 100
So the class with nearest no. to 100 in cumulative frequency table is the median class

Median class = 69.5-74.9

3) cumulative frequency of the class preceding median class= 44

4) Class interval= upper limit - lower limit of any class
= 64.5-59.5
= 5

So the class interval is 5

Hope this help you mate
