Answer 1

Step-by-step explanation:

Here the modal class is 60-70 as modal class has highest frequency i.e., in this case it is 11.

L = lower limit of modal class = 60

f1 = frequency of modal class = 11

f0 = frequency of class preceding the modal class

= 8

f2 = frequency of class succeeding the modal

class = 6

h = size of class interval = 10

mode = L + (f1-f0)*h/(f1-f0)+(f1-f2)

= 60 + 3*10/3+5

= 60 + 30/8

= 60 + 3.75

= 63.75
