8. In a study with 15 transplants for 15 children was reported where ultrasounds were taken at the time of liver
transplant and again 5 to 10 years later to determine the systolic pressure of the hepatic artery. In that example,
Wilcoxon's signed-rank test was applied to compare the hepatic systolic pressures measured at two different times.
Table gives the diastolic presures obtained from the study. Test to compare the mean diastolic hepatic pressures.
Name the test and state clearly your null and alternative hypotheses and choice of test size.
