a. Calculate the difference between each pair of observa-
tions by subtracting observation 2 from observation 1.
Use the differences to calculate x and s.
b. If μ₁ and μ2 are the means of populations 1 and 2, respec-
tively, express μd in terms of μ₁ and μ₂.
c. Form a 95% confidence interval for μd.
d. Test the null hypothesis Ho: pd = 0 against the alterna-
tive hypothesis Ha: Md 0. Use a = .05.
