a. Is there significant evidence that the two treatments differ using an α = .05 paired t test.

b. Is there significant evidence that the two treatments differ using an α = .05 sign test.

c. Do your conclusions in parts (a) and (b) agree?

d. How do your inferences about the two treatments based on the paired t test and based on the sign test differ?
