Solution
It is given that a grouped frequency distribution table of class size 5 has to be constructed. Therefore, the class intervals will be 0−5, 5− 10, 10 −15, 15−20…By observing the data given as above, a grouped frequency distribution table can be constructed as follows.
It can be observed that there are very few engineers whose homes are at more than or equal to 20 km distance from their workplace. Most of the engineers have their work place up to 15 km distance from their homes.
