Use Information 1 to construct a table that show the value t

Use Information #1 to construct a table that show: the value; the frequency; the relative frequency: and the cumulative frequency. Thon draw a combined overlaid cumulative frequency bar chart and cumulative frequency polygon.

Solution

Frequency table is given by:

Where, relative frequency = frequency / total frequency

Cumulative frequency = sum of all frequencies less than and equal to that value.

Cumulative frequency bar chart:

Cumulative frequency polygon:

Value	Frequency	Relative frequency	Cumulative frequency
6	1	0.0476	1
12	1	0.0476	2
14	1	0.0476	3
18	5	0.2381	8
19	1	0.0476	9
20	2	0.0952	11
