Construction of a discrete frequency distribution

Construction of a Discrete frequency Distribution

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
