The Energy Star rating system is an energy efficiency program run by the U.S. Environmental ProtectionAgency (EPA). Energy Star certified appliances, such as televisions and refrigerators, are rated in regard totheir average energy consumption per year.A certain brand of Energy Star certified refrigerator is stated to have a mean yearly electricity cost of$107. A consumer advocacy organization believes that this claim is wrong, that the energy consumption ofthis particular refrigerator is different than $107 per year. The group collected a random sample of 18refrigerators of the model in question and had each lab-tested for electricity consumption. The yearlyenergy consumption of each is given below.106.72107.8106.38107.1107.82106.39106.39106.71107.53107.03106.73106.84107.73106.67106.63107.38106.67106.29Using a significance level of 0.1%, test the hypothesis that the average yearly electricity consumption ofthe refrigerator in question is different than $107 per year. Assume that the distribution of all electricitycosts of this model of refrigerator is approximately normally distributed.
