To test their claim, the company chooses a random sample of 153 of their customers and calculates that these customers used an average of 10,586 kWh of electricity last year. Assuming that the population standard deviation is 2509 kWh, is there sufficient evidence to support the power company's claim at the 0.05 level of significance?
