were made of inert materials (MAT). There were three mice used per scaffold type. The response measure was the percent of glucose phosphated isomerase (Gpi) cells in the region of the wound. A large value is good, indicating that there are many bone marrow cells sent by the body to repair the tissue. ECM Material Gpi (%) ECM1 55 70 70 ECM2 60 65 65 ECM3 75 70 75 MAT1 20 25 25 MAT2 5 10 5 MAT3 10 15 10 (a) Make a table giving the sample size, mean, and standard deviation for each of the six types of material. Is it reasonable to pool the variances? Note that the sample sizes are small and the data are rounded. (b) Run the analysis of variance. Report the F statistic with its degrees of freedom and P-value. What do you conclude?
