Question

following data give the amounts (in dollars) spent on
refreshments by 20 spectators randomly selected from those who attended
a recent baseball game.
4.95 27.99 5.80 2.99 8.00
9.00 15.75 3.05 21.00 9.50
21.77 12.35 10.45 28.45 7.75
19.5 11.65 3.00 16.50 11.45
Use the less-than method to construct a frequency distribution table that
satisfies all properties listed in below.
1. There are 5 classes.
2. The class width is 5.5.
3. The lower boundary of the first class is 2.5.

Answer 1

[2.99, 3.0, 3.05, 4.95, 5.8, 7.75, 8.0, 9.0, 9.5, 10.45, 11.45, 11.65, 12.35, 15.75, 16.5, 19.5, 21.0, 21.77, 27.99, 28.45]

Class width	Frequency
2.5-8.0	7
8-13.5	6
13.5-19	2
19-24.5	3
24.5-30	2

Total 20 samples are thre
