In a study of the accuracy of fast food drive-through orders, one restaurant had 31 orders that were not accurate among 384 orders observed. Use a 0.01 significance level to test the claim that the rate of inaccurate orders is equal to 10%. Does the accuracy rate appear to be acceptable? ... Identify the null and alternative hypotheses for this test. Choose the correct answer below. OA. Ho: p *0.1 H₁: p=0.1 OB. Ho: p=0.1 H₁: p<0.1 OC. Ho: p=0.1 H₁: p=0.1 O D. Ho: p=0.1 H₁: p>0.1 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to 10%. OB. Fail to reject Ho. There is not sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to 10%. OC. Reject Ho. There is sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to 10%. O D. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to 10%.
