Basic Math

In a study of the accuracy of fast food​ drive-through orders,one restaurant had 32 orders that were not accurate among 398orders observed. Use a 0.10 significance level to test the claimthat the rate of inaccurate orders is equal to​ 10%. Does theaccuracy rate appear to be​ acceptable?

Identify the null and alternative hypotheses for this test.Choose the correct answer below.

A. H0​: p≠0.1 H1​: p=0.1

B. H0​: p=0.1 H1​: p≠0.1

C. H0​: p=0.1 H1​: p<0.1

D. H0​: p=0.1 H1​: p>0.1

Identify the test statistic for this hypothesis test.

The test statistic for this hypothesis test is _____ (Round totwo decimal places as​ needed.)

Identify the​ P-value for this hypothesis test.

The​ P-value for this hypothesis test is _____ ​(Round to threedecimal places as​ needed.)

Identify the conclusion for this hypothesis test.

A. Reject H0. There is not sufficient evidence to warrantrejection of the claim that the rate of inaccurate orders is equalto​ 10%.

B. Fail to reject H0. There is sufficient evidence to warrantrejection of the claim that the rate of inaccurate orders is equalto​ 10%.

C. Reject H0. There is sufficient evidence to warrant rejectionof the claim that the rate of inaccurate orders is equal to​10%.

D. Fail to reject H0. There is not sufficient evidence towarrant rejection of the claim that the rate of inaccurate ordersis equal to​ 10%.

Does the accuracy rate appear to be​ acceptable?

A. Since there is sufficient evidence to disprove the theorythat the rate of inaccurate orders is equal to​ 10%, the accuracyrate is acceptable.

B. Since there is not sufficient evidence to disprove the theorythat the rate of inaccurate orders is equal to​ 10%, it is possiblethat the accuracy rate is acceptable.

C. Since there is sufficient evidence to disprove the theorythat the rate of inaccurate orders is equal to​ 10%, the accuracyrate is not acceptable. The restaurant should work to lower thatrate.

D. Since there is not sufficient evidence to disprove the theorythat the rate of inaccurate orders is equal to​ 10%, the accuracyrate is not acceptable. The restaurant should work to lower thatrate
