In 1993, Toyota introduced the Supra sports car, which was designed to have 320 horsepower in stock configuration. A computer chip modification for the fuel injection system was later introduced that was claimed to increase horsepower. To check whether the chip actually does increase horsepower, we sample six stock 1993 Supras and record each vehicle’s horsepower (the results appear below).

​

Car number123456
Stock hp315321325318320321

​

Next, technicians install the computer chip in each of the six vehicles’ electronic injection systems and then record the horsepower of each (the results appear below).

​

Car number123456
Modified hp320320328325323323

​

Find a 95% confidence interval on the population mean horsepower difference associated with the chip modification.
