Question

2. Multiple myeloma, or blood plasma cancer, is characterized by increased blood vessel formulation 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 measurements were taken immediately prior to the stem cell transplant and at the time the complete response was determined. At the 0.05 level of significance, is there evidence that the mean bone marrow microvessel density is higher before the stem cell transplant than after the stem cell transplant? Hint: use PairedMean-T-Test.xlsx.

Patient	Before	After
1	158	284
2	189	214
3	202	101
4	353	227
5	416	290
6	426	176
7	441	290
