2.5. Create a frequency table for miles driven using five categories and with the first-class having a lower limit of 1.

Answer 1

Result:

2.5. Create a frequency table for miles driven using five categories and with the first-class having a lower limit of 1.

Maximum value is 90 and for the number of classes of 5, we need the class width of 90/5 = 18. For convenience, we take class width of 20.

	Class width	frequency	percent
	1-20	12	30.0
	21-40	11	27.5
	41-60	7	17.5
	61-80	7	17.5
	81-100	3	7.5
		40	100.0
