Let μB = the true cost of an oil change for all BMWs and μT = the true cost of an oil change for all Tahoes. What are the appropriate hypotheses for this test? Check all that apply.

If we tested at the = 0.01 significance level, we would H0 because the P-value (which is between 0.01 and 0.02) is = 0.01.

We convincing evidence that the true mean cost of an inspection on the West Coast is greater than the mean cost of an inspection on the East Coast.

If we tested at the = 0.01 significance level, we would H0 because the P-value (which is between 0.01 and 0.02) is = 0.01.

Which statements are true about the Random and 10% conditions? Check all that apply.

Select all statements that are true when making the decision about a test using = 0.01 versus = 0.05.A test that rejects H0 at = 0.05 will always reject at = 0.01.A test that rejects H0 at = 0.05 will sometimes reject at = 0.01.A test that rejects H0 at = 0.05 will never reject at = 0.01.A test that rejects H0 at = 0.01 will always reject at = 0.05.A test that rejects H0 at = 0.01 will never reject at = 0.05.

Decision: H0
