The following data represent the lengths of time, in months, for a tumor to recur after chemotherapy

19	18	17	1	21	22	54
46	25	49	50	1	59	39
43	39	5	9	38	18	14

Answer 1

Limits 1 59 Midpoint/median 28

Boundries 1-10 11-20 21-30 31-40 41-50 51- 60

Frequencies 5 9 6 7 11 4

relative freq 12% 21% 14% 17% 26% 10%

cum freq 12% 33% 48% 64% 90% 100%

This is a quick table. It wasn't specified what the size of the classes were to be, I picked 10. Nor was the format of the table specified. However, the information needed is there.
