The U.S. Energy Information Administration claimed that U.S. residential customers used an average of 10,996 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 138 of their customers and calculates that these customers used an average of 11,374 kWh of electricity last year. Assuming that the population standard deviation is 3030 k Wh, is there sufficient evidence to support the power company's claim at the 0.10 level of significance? Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places. Answer Tables Keypad Keyboard Shortcuts
