When asked to conduct a statistical analysis/test you should include, as appropriate: 1) The name of the test and any assumptions, 2) null and alternate hypotheses, 3) whether the test is one or two-tailed, 4) the test statistic, its value, and any calculations used in obtaining that value, 5) the associated P-value and any calculations used in obtaining that value, 6) the degrees of freedom and critical value, 7) your conclusion with respect to both the statistical hypotheses and the biological (or scientific) hypotheses. Q2. Researchers are interested in the variability in the efficacy of a new chemotherapy drug. Three samples are taken from each of five different tumors, treated with the new drug, and the growth rate measured.

a) Perform an statistical analysis to determine the proportion of the variance that is due to variation among tumors. Assume any assumptions are met.

b) A previous study found a value of 0.75 using a similar experiment with a different drug. What does this mean for the variability in the efficacy of the new drug?
