15 healthy adult subjects were asked to walk on a treadmill while connected to monitors. One of two kinds of disturbances was applied during the walk, and the number of steps until adaptation was recorded. Each subject experienced both kinds of disturbance, in random order and the researchers computed the difference between the two disturbances and were interested if the mean effect of the first disturbance was greater than the mean effect of the second. a. State the hypotheses to be tested. b. The test resulted in a t-value of 2.05 with 14 degrees of freedom. Compute the P-value
