A manufacturer claims that the mean lifetime of its lithium batteries is 1500 hours. A homeowner selects 25 of these batteries and finds the mean lifetime to be 1470 hours with a standard deviation of 80 hours. Test the manufacturer's claim. Use a = 0.05. Round the test statistic to the nearest thousandth.
