In a study of the accuracy of fast food​ drive-through orders, one restaurant had 40 orders that were not accurate among 315 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?

In a study of the accuracy of fast food​ drive-through orders, one restaurant had 40 orders that were not accurate among 315 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.
O A. Ho: p= 0.1
H1: p>0.1
О В. Но: р30.1
H1:p<0.1
ОС. Но: р#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 Hn. There is not sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to 10%.
O B. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to 10%.
O C. Reject Hn. There is not sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to 10%.
O D. Reject Hn. There is sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to 10%.
Does the accuracy rate appear to be acceptable?
O A. Since there is sufficient evidence to reject the claim that the rate of inaccurate orders is equal to 10%, the inaccuracy rate is acceptable.
O B. Since there is sufficient evidence to reject the claim that the rate of inaccurate orders is equal to 10%, the inaccuracy rate is unacceptable, so the restaurant should work to lower that rate.
O C. Since there is not sufficient evidence to reject the claim that the rate of inaccurate orders is equal to 10%, it is plausible that the inaccuracy rate is 10%. This rate would be too high, the restaurant should work to lower the rate.
