6. [18pts.] Wind Power. Windlogics is a company that specializes in providing expert advice and solutions for wind energy. One of the services they provide is forecasts for wind to help determine predictions of power output by wind turbines. One simple quantity they are interested in (to validate their model) is the average wind speed for the day in a particular region (say Story county). For a variety of reasons, it is very difcult to measure the average wind speed for a day across an entire region. For their Story county unit, on October 31, 2015, Windlogics takes a simple random sample of size 289 and calculates a mean wind speed of 13 mph. Based on their expertise, Windlogics knows the standard deviation of wind speed in Story county during the fall is 11 mph. (A) [2pts.] What is the population parameter of interest in the context of this problem? The mean wind Speed in Story county on 10/31/15 1pt. for \"mean\" and 1pt for \"wind speed\" [6pts.] Based on this information, provide a 93% condence interval for the population param- eter of interest. Show work here: 11 28 13 :I: 1.81 :1: => (11.829,14.171) is the 93% CI 3 Final Answer: (11.829, 14.171) 2pts. for correct zscore, partial credit depending on circumstances, 3pts. for correctly setting up the CI and 1pt. for for correctly stating lower bound followed by upper bound
