Question Text	The article "Performance Test Conducted for a Gas Air-Conditioning System" (American Society of Heating, Refrigerating, and Air Conditioning Engineering [1969]: 54 ) reported the following data on maximum outdoor temperature $(x)$ and hours of chiller operation per day $(y)$ for a 3 -ton residential gas air-conditioning system: $x y 72 4.8 78 7.2 80 9.5 86 14.5 88 15.7 92 17.9$ Suppose that the system is actually a prototype model, and the manufacturer does not wish to produce this model unless the data strongly indicate that when maximum outdoor temperature is $8 2^{\circ} F$ , the true average number of hours of chiller operation is less than $12.$ The appropriate hypothesis is then $H_{0} : α + β (82) = 12 versus H_{a} : α + β (82) < 12$
