A manufacturer claims that the mean lifetime of its lithium batteries is 1101 hours. A homeowner selects 25 of these batteries and finds the mean lifetime to be 1081 hours with a standard deviation of 81 hours. Test the manufacturer's claim. Use a = 0.05. OA. p-value = 0.114 > 0.05; do not reject the Ho; there is enough evidence to support the claim. OB. p-value = 0.114 > 0.05; reject the Ho; there is not enough evidence to support...
