Overall, the difference between the original value of the mean (0.8) and the new value of the mean (-0.4) may be summarized by (0.8 - 1.0)*2 = -0.4. The mean of the sum of two random variables X and Y is the sum of their means: For example, suppose a casino offers one gambling game whose mean winnings are -$0.20 per play, and another game whose mean winnings are -$0.10 per play.
What is Gleevec? Gleevec (imatinib) interferes with the growth of some cancer cells. Gleevec is used to treat certain types of leukemia (blood cancer), bone marrow disorders, and skin cancer, or certain tumors of the stomach and digestive system. Gleevec may also be used for purposes not listed in this medication guide.
But if recent history is a lesson, that may not help bring down the price much. When Gleevec, a miraculous drug to effectively treat a certain type of leukemia, was released in 2001, people at first choked at its $30,000 annual price tag.
