Q2) Multiple myeloma, or blood plasma cancer, is characterized by increased blood vessel formulation (angiogenesis) in the bone marrow that is a predictive factor in survival. One treatment approach used for multiple myeloma is stem cell transplantation with the patient's own stem cells. The data stored in Myeloma, and shown in the right column represent the bone marrow micro-vessel density for patients who had a complete response to the stem cell transplant (as measured by blood and urine tests}. The measurements were taken immediately prior to the stem cell transplant and at the time the complete response was determined. Patient Before After 1 17B 334 2 1 19 214 3 102 346 4 153 327 5 330 490 6 206 276 7 214 509 At the 0.01 level of signicance, is there evidence that the mean bone marrow micro-vessel density is lower before the stem cell transplant than after the stem cell transplant?
