A group reported the accompanying annual rainfall (in inches) for a particular city in Oregon over a 59 year period.

28.84	20.15	19.88	25.72	16.42	21.18	28.96	20.72	23.58	10.62
20.85	19.86	23.34	19.08	29.23	19.320	20.27	19.93	15.47	20.68
23.43	19.55	20.82	19.04	18.77	19.63	12.39	22.39	15.95	20.46
16.05	22.08	19.44	30.38	18.79	10.89	17.25	14.95	13.86	15.30
13.71	14.68	15.16	16.77	12.33	21.93	31.57	18.13	28.87	16.69
18.81	16.15	18.16	19.99	19.00	23.97	21.99	17.25	14.07

(a)

Construct a relative frequency distribution for the city's rainfall data. (Round your answers to four decimal places.)

Annual Rainfall	Relative Frequency
10 to <12	1
12 to <14
14 to <16
16 to <18
18 to <20
20 to <22
22 to <24
24 to <26
26 to <28
28 to <30
30 to <32

Answer 1

According to Formula : Relative Frequency = Frequency / Total(Frequency)

Here,

Total(Frequency) = 59

Annual Rainfall	Frequency	Relative Frequency
10 to <12	2	0.0339
12 to <14	4	0.0678
14 to <16	7	0.1186
16 to <18	7	0.1186
18 to <20	16	0.2712
20 to <22	10	0.1695
22 to <24	6	0.1017
24 to <26	1	0.0169
26 to <28	0	0
28 to <30	4	0.0678
30 to <32	2	0.0339
