I have been trying this question and I keep getting parts of it incorrect. The top is the problem I am working on the bottom is the remainder of the problem from a previous one I got wrong. I am confused and would like to know the functions to use in excel. Thank you very much

Increased blood vessel formulation is a predictive factor in survival for a certain disease. One treatment is stem cell transplantation with the patient's own stem cells. The accompanying data table represents 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. Click the icon to view the data table. a. At the 0.10 level of significance, is there evidence that the mean microvessel density is higher before the stem cell transplant than after the stem cell transplant? Let u, be the mean density before the transplant and let u2 be the mean density after the transplant. State the null and alternative hypotheses. Choose the correct answer below. A. Ho: HD SO (where HD = H1 - H2) O B. Ho: HD 20 (where HD = H1 - H2) H 1 : HD > 0 H1: HD 0 (where HD = H1 - H2) H1: HD # 0 H1 : HD SO O E. Ho: HD #0 (where HD = H1 - H2) OF. Ho: HD U -c. Ho:pDlJ(wherepD=p1-pz) H1:pD20 H1IHD50 -t:. HomDsGtwhere HD=P1'|-l2) r. Ha:pDaO(wherepD=p1-p2] H1I|JD= H11|JD
