3. Rehabilitation therapy (Cont'd). a. Estimate the contrast L = (#1 - /2) -(2 -/3) with a 99% confidence interval. Interpret your interval estimate. (Please show your work) b. Estimate the following using the Bonferroni's procedure with a 95% familywise confidence coefficient: D1 = p1 - H2, D3 = H2 - #3. D2 = HI - 13, LI = D1 - D3. Interpret your interval estimates. (Please show your work) c. Would the Scheffe's procedure have been more efficient to use in part (b) than the Bonferroni's procedure? Explain. d. Would the Tukey's procedure have been applicable for the task in part (b)? Explain
