Stat 135, Fall 2006 A. Adhikari HOMEWORK 6 (due Friday 10/13) 1. 9.3. Do b accurately using R . Say what the limiting power is as p approaches 0.5; also say what the limiting power is as p approaches 0 and 1. 2. 9.11. Again, use R to do the plots. In each case, say what the limiting power is as μ approaches 0. 3. 9.12. 4. 9.13. In c , use R to find the critical values x 0 and x 1 . 5. 9.20. 6. 9.24. In e , also use R to find the exact significance level. 7. 11.1. Turn the page for d-h . 8. 11.16. You should be able to solve an inequaltiy for n , but if you can’t, don’t forget other less elegant methods! 9. This question is from Statistics by Freedman, Pisani, and Purves, the text used in our lower division classes. Five planets were known to the ancient world: the inner planets Mercury and Venus, and the outer planets Mars, Jupiter, and Saturn. The densities of the planets are given below, relative to the density of the Earth which is taken as 1. The inner planets have an average density of 0.81, while the outer planets have an average density of 0.36. Does it make sense to ask if the difference is statistically significant? If so,

### What students are saying

• 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.
