36-226 HOMEWORK 8 Due: Monday 4/11/16 at 9:30am in class Remember to show all work ; just writing down the answer will not receive credit. 1. Exercise 10.2 in Wackerly. 2. Exercise 10.6 in Wackerly. 3. Altered Wackerly 10.17 Briefly, we’re interested in the amount of breaststroke training (in meters) for two types of competitive swimmers: those who specialize in breaststroke and those who specialize in the individual medley (all four strokes). The training habits of two groups of swimmers (Group 1 = breaststroke; Group 2 = IM) were analyzed, giving the following information: n 1 = 130; ¯ x 1 = 9017m; s 2 1 = 7162 2 n 2 = 80; ¯ x 2 = 5853m; s 2 2 = 1961 2 (a) Test the null hypothesis that the breaststroker group averages 10,000m a week of breaststroke training against the alternative of not 10,000m (steps on next page) . Write down your null and alternative hypotheses. Find the Rejection Region for α = 0 . 05 and α = 0 . 10. Calculate your test statistic. Find the exact p-value for your test statistic using R and an approximate p-value using Table 4, Appendix 3.

### 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.
