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.
