a [Should we build a wind farm?] Wind Power has been the most popular alternative energy choice in recent years. One of the key determinants for choosing a location for a wind farm is whether the site has enough wind. To produce enough energy using current technology, the site should have an annual average wind speed exceeding 9.5 miles per hour, according to the Wind Energy Association. One candidate site in southern California was monitored for a year, with wind speeds recorded every 6 hours. A total sample of 1,258 reading of wind speed averaged 9.726 mph with a sample standard deviation of 6.11 mph. The histogram of these 1,258 readings is shown below. You are asked to perform statistical analysis to help the developer decide whether to place a wind turbine at this site.

[2 pts) What are the appropriate conclusion and interpretation based on the outcome of the hy test at the 5% significance level? Should you recommend building a wind farm at this site? Conclusion of the test: Interpretation: 13. [2 pts) The board feels that the 5% significance level might be too harsh and wishes to i claim is supported with relative weaker evidence. Your manager asked you to change the level to either a = 1% or a = 10%. Which one would you choose to make the null hypoth be rejected? With the new significance level, would you recommend building a wind farm an New significance level: Your recommendation
