The authors of a paper studied patients who had been diagnosed with stage 2 multiple myeloma prior to the age of 50. For each patient who received high dose chemotherapy, the number of years that the patient lived after the therapy (survival time) was recorded. The cumulative relative frequencies in the accompanying table were approximated from survival graphs that appeared in the paper.

Years Survived. Cumulative Relative Frequency

0 to<2 0.10

2 to<4 0.45

4 to<6 0.54

6 to<8 0.59

8 to<10 0.68

10 to<12 0.70

12 to<14 0.79

14 to<16 1.00

Use the cumulative relative frequency plot from part (a) to answer the following questions. (Enter your answers to two decimal places.)

(i)

What is the approximate proportion of patients who lived fewer than 5 years after treatment?

(ii)

What is the approximate proportion of patients who lived fewer than 7.5 years after treatment?

(iii)

What is the approximate proportion of patients who lived more than 10 years after treatment?
