This data set has two groups of leukemia patients:
one group of 21 persons has received a certain treatment (rx=0);
the other group of 21 persons has received a placebo (rx=1).
1) Compare survival time vs.:
Male
Female
Treatment rx=0
Treatment rx=1
2) Compare survival time vs. white blood cell count
