1. There is a new drug that is used to treat leukemia. The following data
represents the remission time in weeks for a random sample of 21
patients using the drug.
1. The r value between variables 4 and 9 is r = -0.32.
2. The negative r value indicates that a negative relationship exists when one variable increases and
the other variable decreases. This r value of r = -0.32 has moderate strength since 0.3 < r < 0.5,
