QUESTION 12 [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 15 miles per hour, according to the Wind Energy Association. Your team was asked to perform statistical analysis at a candidate site in Texas to help the developer decide whether to place a wind turbine at this site. Let u denote the average wind speed at the candidate site. Based on the information, what should be the appropriate null and alternative hypotheses for the purpose of your analysis? O a. Hop = 11; Hail > 11. O b. Hoit = 15; Haim # 15. O ". Hoi H > 15; Hail = 15. O d. Hoit = 15; Hail > 15. QUESTION 13 [Cola-Coca] Cola-Coca needs their automatic filling machines to put on average 20 ounces of soda into each bottle. Shutting down the machine is very costly, but the company will do this if there is very strong evidence that the fill rate is significantly different than 20 ounces (both underfilling and overfilling). Let u denote the average volume of soda filled in each bottle. Based on the information, what should be the appropriate null and alternative hypotheses for the purpose of your analysis? O a. Hoip = 20; Hai p not equal to 20. O b. Hoi H = 20; Hai H 20. QUESTION 14 [Order kiosk at Burger King] If the order kiosk at the Dallas store is well-received, Burger King is considering placing order kiosks in all of their high-performing stores by the end of the year. The corporation will go forward if there is very convincing evidence that on average more than 359% of all customers use the kiosk. They collected data for one week at the Dallas store and found that 900 of 2,500 customers used the kiosk. Let p denote the population proportion of customers who use the kiosk. Based on the information, what should be the appropriate null and alternative hypotheses for the purpose of the analysis? O a. Hop s 359%; Hai p > 3596. O b. Hoi p = 3096; Hai p > 3096. O C. Hoip = 3596; Hai p 3696
