Increased blood vessel formulation is a predictive factor in surVival tor a certain disease One treatment is stem cell transplantation with the patient's own stem cells The accompanying data table represenE the microvessel density for patients who had a complete response to the stem cell transplant The measurements were taken immediately prior to the stem cell transplant and at the time the complete response was determined. Complete parts (a) through (d) below. a Click the icon to View the data table. a. At the 0.05 level of signicance. is there evidence that the mean micrpvessel density is higher before the stem cell transplant than aer the stem cell transplant? Let p1 be the mean density before the transplant and let p2 be the mean density after the transplant. State the null and alternative hypotheses. Choose the correct answer below.
