Application Exercise: A given strain of mice were injected with the same amount of tumor pulp that came from a large tumor excised from another mouse. After the tumor injections, the mice were then randomly injected with one of two chemotherapy treatments (G or C). Twenty:I days after the chemotherapy injection, the tumor volumes [in cubic centimeters) were measured. Researchers hypothesize that treatment G will be less effective than treatment C. What can be concluded with an a of 0.01? The results are below: treatment treatment G C l = 0.62 z = 0.50 31 = 0.10 32 = 0.27 n1 = 9 n2 =
