17.41 The placebo effect. To understand the workings of the placebo effect, scientists measure activity at a key point in the brain when patients receive a placebo that they think is an active drug and also when no treatment is given. The same 6 patients are measured both with and without the placebo, at different times.

a. Explain why the proper procedure to compare the mean response to the placebo with the mean response to the control (no treatment) is a matched pairs t test.

b. The six differences (treatment minus control) had [x-bar] = -0.326 and s = 0.181. Is there significant evidence of a difference between treatment and control at significant level a = 0.05?
