Question: Compute the 90% rank-sum CI for 1 - 2 using the data in Exercise 11. In Exercise 11 In an experiment to compare the bond

Compute the 90% rank-sum CI for μ1 - μ2 using the data in Exercise 11.
In Exercise 11
In an experiment to compare the bond strength of two different adhesives, each adhesive was used in five bondings of two surfaces, and the force necessary to separate the surfaces was determined for each bonding. For adhesive 1, the resulting values were 229, 286, 245, 299, and 250, whereas the adhesive 2 observations were 213, 179, 163, 247, and 225. Let μi denote the true average bond strength of adhesive type i. Use the Wilcoxon rank-sum test at level .05 to test H0: μ1 = μ2 versus Ha: μ1 > m2.
