High-powered experimental engines are being developed by the Hendrix Motor Company for use in their new sports coupe. The engineers have calculated the maximum horsepower for the engines to be 620 HP. Sixteen engines are randomly selected for testing. Perform a hypothesis test to determine whether the data suggests that the average maximum horsepower for the experimental engine is significantly different than the maximum horsepower calculated by the engineers. Assume the data are normally distributed and use a significance level of 0.05. 663 576 Maximum Horsepower (HP) 657 641 591 581 602 666 601 645 594 575 575 591 597 574 Copy Data Step 2 of 3: Compute the value of the test statistic.
