=+8.14. How would you find the confidence-interval end points for the parameter of in- terest when the interval has confidence level nearest 0.90 and corresponds to:

(a) The sign text with n = 11

(b) The Wilcoxon signed-rank test with n = 11

(c) The Wilcoxon rank-sum test with m = 5, n = 6 In each case define the function Z of the observations, give the numerical values of L and U for the order statistics Z(L) and Z(U), and give the exact confidence level.
