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 α = 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...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
