Create a frequency table should include class interval, frequency, relative frequency and cumulative relative frequency. NO intervals overlapping!

Make a histogram based on table.

Answer 1

Class interval	Frequency	Relative frequency	Cumulative Frequency
10 - 24	7	7 / 50 = 0.14	7
25 - 39	14	14 / 50 = 0.28	21
40 - 54	7	7 / 50 = 0.14	28
55 - 69	4	4 / 50 = 0.08	32
70 - 84	5	5 / 50 = 0.1	37
85 - 99	3	3 / 50 = 0.06	40
100 - 114	4	4 / 50 = 0.08	44
115 - 129	2	2 / 50 = 0.04	46
130 - 144	4	4 / 50 = 0.08	50
Total	50	1.0000
