Question

In a study of the accuracy of fast food​ drive-through orders, one restaurant had 31 orders that were not accurate among 399 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.
 
 
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=
 
 
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.
 
A.
Reject H0. There is sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to​ 10%.
 
B. Fail to reject H0. There is sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to​ 10%.
Your answer is not correct.
 
C. Reject H0. There is not sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to​ 10%.
 
D. Fail to reject H0. There is not 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?
 
A. Since there is not sufficient evidence to reject the claim that the rate of inaccurate orders is equal to​ 10%, the restaurant should work to increase that rate.
 
B. Since there is sufficient evidence to reject the claim that the rate of inaccurate orders is equal to​ 10%, the inaccuracy rate is acceptable.
 
 
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 so the restaurant should work to lower the rate.
D. 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.
