The water tax bills (in rupees) of 30 houses in a locality are given below. Construct a grouped frequency distribution with class size of 10. 30,32,45,54,74,78,108,112,66,76,88,40,14,20,15,35,44,66, 75,84,95,96,102,110,88,74,112,14,34,44

Text Solution

Verified by Experts

Here the minimum value of class is '14.'
and maximum value is '112'
Now, Making the class interval of size 10. So, we can make class-interval: '14-23, 24-33,..., 104-113.'
Thus, we have '11' class interval.
