1) Consider the following hypothesis test for the mean difference. (Give your answers correct to four decimal places.)

Determine the p-value for H_o: _d = 0 and H_a: _d > 0, with n = 25 and t = 1.95.

Determine the p-value for H_o: _d = 0 and H_a: _d 0, with n = 16 and t = -1.92. Determine the p-value for H_o: _d = 0 and H_a: _d < 0, with n = 28 and t = -2.55. Determine the p-value for H_o: _d = 0.75 and H_a: _d > 0.75, with n = 13 and t = 3.47.

2) Consider the following set of data.

Pairs	1	2	3	4	5
Sample A	7	3	4	8	1
Sample B	1	3	7	2	6

(a) Find the paired differences, d = A - B, for this set of data. (d₁) (d₂) (d₃) (d₄) (d₅) Find the mean d of the paired differences. (Give your answer correct to one decimal place.) Find the standard deviation s_d of the paired differences. (Give your answer correct to two decimal places.)
