Question

Prepare a frequency distribution table for the following, using class intervals 0 - 9, 10 - 19, ...

23, 38, 40, 57, 74, 31, 47, 52, 56, 59, 44, 56, 18, 46, 63, 57, 79, 39, 39, 20, 39, 45, 49, 60, 32, 47, 19, 69, 20, 5, 8, 53, 28, 48, 73, 77, 63, 52, 65, 11

Sum

Solution

Class Interval	Tally Marks	Frequency
0 - 9	`bb\|bb\|`	2
10 - 19	`bb\|bb\|bb\|`	3
20 - 29	`bb\|bb\|bb\|bb\|`	4
30 - 39	`cancel(bb\|bb\|bb\|bb\|) bb\|`	6
40 - 49	`cancel(bb\|bb\|bb\|bb\|) bb\|bb\|bb\|`	8
50 - 59	`cancel(bb\|bb\|bb\|bb\|) bb\|bb\|bb\|`	8
60 - 69	`cancel(bb\|bb\|bb\|bb\|)`	5
70 - 79	`bb\|bb\|bb\|bb\|`	4
