The manufacturer claims that your new car gets 32 mpg on the highway with the population standard deviation, o = 5.5 mpg. You suspect that the mpg is more for your car. A random sample of 25 trips on the highway that you found the sample average was 33.3 mpg. At a = 0.05, apply the 4-step hypothesis testing. Step 1: state the hypotheses, and identify the claims (3 Points) Ho:- Ha: H Step 2: compute the test statistic Z Ho G√ Step 3: find the P-value Step 4: conclude (3 Points) (2 Points) (2 Points) The manufacturer claims that your new car gets 32 mpg on the highway with the population standard deviation, o = 5.5 mpg.
