select an appropriate statistical test and perform hypothesis testing 4. It is claimed that a car is driven on the average is no more than 20,000 kilometers peryear. To test this claim, a random sample of 100 car owners were asked to keep a recordof the kilometers they travel. Would you agree with this claim if the random sampleshowed an average of 23, 500 with a standard deviation of 3,900 kilometers? Use a =0.05.

Solution-: Given: x¯=23500,μ0=20000,n=100,s=3900,α=0.05 We select an appropriate statistical test…

Answered: It is claimed that a car is driven on…

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 650HP. 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. Maximum Horsepower (HP) 634 607 688 630 695 635 657 655 678 671 676 689 672 687 680 677 Copy Data Step 2 of 3 : Compute the value of the test statistic. Round your answer to three decimal places.
