Expert Solution
Step 1
Steps to decide the Class Size:
1) Find the max and the min number; in our case, Max= 537 & Min= 50
2) Measure the difference between them & divide it by "no. of classes":
(537-50)/6 = 81.16
3) Round it up to get the Class Size=82
Relative Frequency = (frequency of a particular class)/()
Mid point of a class = (upper limit + lower limit)/2
Number of values (n)=29
