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 tablerepresents 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 timethe complete response was determined. Complete parts (a) through (d) below.Click the icon to view the data table.a. At the 0.01 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 ₂ be the mean density after the transplant.

Please provide Complete and clear solution The manager of a fleet automobiles is testing two brands of radial tires and assigns one tire of each brand at random to the two rear wheels of eight cars and runs the cars until the tires wear out. The data (in kilometers) follow. Car Brand 1 Brand 2 1 36,925 34,318 2 45,300 42,280 3 36,240 35,500 4 32,100 31,950 5 37,210 38,015 6 48,360 47,800 7 38,200 37,810 8 33,500 33,215 Do the data suggest that the two brands of radial tires prove the same mean life?
