The engineers at Ryobi have developed a new and faster charger for their 40-volt batteries used for their cordless lawn mowers. The engineers claim the new charger will charge a discharged battery in less than an average time of 68 minutes. Vince Lawn decides to test this claim and purchases the charger and a new 40-volt battery for his cordless lawn mower. He uses his cordless lawn mower 38 times throughout the year to cut his lawn and each time he makes sure the battery is completely discharged before he puts it on the charger. He finds that the mean time it takes the battery to fully recharge is 64 minutes with a standard deviation of 10.9 minutes. Using Vince Lawn's results, test the engineers claim at the 0.01 level of significance. (Show all steps.)
