Question
The U.S. Energy Information Administration claimed that U.S. residential customers used an average of 10,092 kilowatt hours (kWh) of electricity this year. A local power company believes that residents in their area use more electricity on average than EIA's reported average. To test their claim, the company chooses a random sample of 189 of their customers and calculates that these customers used an average of 10,628 kWh of electricity last year. Assuming that the population standard deviation is 2970 kWh, is there sufficient evidence to support the power company's claim at the 0.02 level of significance? Step 3 of 3: Draw a conclusion and interpret the decision.
