A certain type of battery supercharger was found to take a mean of 13.8 minutes to charge a standard electric vehicle (EV) battery. A firmware update for this type of supercharger was recently released, but the update has received negative reviews from users. A researcher suspects the mean time the updated superchargers take to charge a standard EV battery is greater than 13.8 minutes. To test his claim, he chooses 23 of the updated superchargers at random and measures the time it takes each one to charge a standard EV battery. He finds that the superchargers take a sample mean of 14.1 minutes to charge a standard EV battery, with a sample standard deviation of 3.3 minutes. Assume that the population of amounts of time to charge a standard EV battery using the updated superchargers is approximately normally distributed. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to support the claim that

, the mean time the updated superchargers take to charge a standard EV battery, is more than 13.8 minutes.A certain type of battery supercharger was found to take a mean of 13.8 minutes to charge a standard electric vehicle (EV) battery.
