Step-by-step explanation:
A small startup company wishes to know how many hours, per week, that its employees spend commuting to and from work. The number of hours for each employee are shown below. Construct a frequency table for grouped data using four classes.
9, 18, 18, 14, 13, 4, 12, 9, 13, 10, 20, 12, 19, 20, 13, 3, 5, 20, 17, 1
Since we have to grouped data into four classes,let us take classes as
0-5: this class includes (1,3,
4)
5-10 :this class includes (5,9,9)
10-15: this class includes (14,13,12,13,10,12,13)
15-20 :this class includes (18,18,20,19,20,20,17)
(exclusive classes;i.e. upper limit not included )
Number of hour_______frequency
0-5____________________3
5-10___________________3
10-15__________________7
15-20__________________7
Hope it helps you.
