3. Here's a new idea for treating advanced melanoma, the most serious kind of skin cancer: Genetically engineer white blood cells to better recognize and destroy cancer cells, and then infuse these cells into patients. The subjects in a small initial study of this treatment were 11 patients whose melanoma had not responded to existing treatments. One question was how rapidly the new cells would multiply after infusion, as measured by the doubling time (in days). Here are the doubling times: 1.4 1.0 1.3 1.0 1.3 0.8 0.7 (a) Identify what the statistician is trying to find (confidence interval or hypothesis test). (b) Which procedure (z or t) he/she/they should use to find it. (c) Complete the inference.
