Some longer stays are also approximated as 15 hors in this table Hours Count Percent 1 14 2.80 56 11.20 2 3 82 16.40 4109 21.80 5 88 17.60 6 61 12.20 7 36 7.20 8 19 3.80 9 18 3.60 10 10 2.00 15 7 1.40 Determine the cumulative distribution function for the random variable 1 sx<2 F(x)

Answer 1

x	x < 1	1 <= x < 2	2 <= x < 3	3 <= x < 4	4 <= x < 5	5 <= x < 6
F(x)	0	0.028	0.140	0.304	0.522	0.698

x	6 <= x < 7	7 <= x < 8	8 <= x < 9	9 <= x < 10	10 <= x < 15	15 <= x
F(x)	0.82	0.892	0.93	0.966	0.986	1
