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 560 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 0.01. 591 601 536 602 Maximum Horsepower (HP) 535 573 584 597 547 591 554 610 Copy Data Step 2 of 3: Compute the value of the test statistic.
