A primer paint can be used on aluminum panels. The primer's drying time is an important consideration in the manufacturing process. Twenty panels are selected, and the drying times in hours are as follows: 1.6, 1.3, 1.5, 1.6, 1.7, 1.9, 1.8, 1.6, 1.4, 1.8, 1.9, 1.8, 1.7, 1.5, 1.6, 1.4, 1.3, 1.6, 1.5, 1.8. Use the Wilcoxon signed-rank test. Is there evidence that the mean drying time of the primer exceeds 1.5 hours? Use a = 0.05. Match the answers. a. Hi u = 1.5 H; u > 1.5 Parameter of interest: Null and Alternative Hypothesis: v Reject the Null Hypothesis if: b.w = max (w +,w¯) =126 Computation: w += 126 Conclusion: w- = 27 c.w swi.05.=17 = 34 d.
