The authors of the paper "Myeloma in Patients Younger than Age 50 Years Presents with More Favorable Features and Shows Better Survival" (Blood [2008]: 4039-4047) 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.
a. Use the given information to construct a cumulative relative frequency plot.
b. Use the cumulative relative frequency plot from Part (a) to answer the following questions:
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?
