Homework 9 (due April 25) 1. Find the critical values for the sign test for the sample size of 15 by computing the P-values like we did in class. Obtain the results for the following values of α (for the 2-sided alternative): 0.01, 0.02, 0.05, 0.10, 0.25. 2. Suppose you ran a sign test on the difference of two medians based on the following paired sample pop 1 110 115 134 95 152 100 149 87 120 170 135 160 166 146 109 pop 2 140 105

Use = 0 . 05. What is the P-value? 3. Now test the same hypothesis (from problem 2) using the Wilcoxon signed rank test. Does the conclusion change? If it does, which result would you trust more? 1...
