a. Use the cumulative relative frequencies given in the previous exercise to compute the relative frequencies for each class interval and construct a relative frequency distribution.
b. Summarize the survival time data with a histogram.
c. Based on the histogram, write a few sentences describing survival time of the stage 2 myeloma patients in this study.
d. What additional information would you need in order to decide if it is reasonable to generalize conclusions about survival time from the group of patients in the study to all patients younger than 50 years old who are diagnosed with multiple myeloma and who receive high dose chemotherapy?
