Question
n a study of the accuracy of fast food​ drive-through orders, one restaurant had
36
orders that were not accurate among
324
orders observed. Use a
0.05
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<0.1
Identify the test statistic for this hypothesis test.
 
The test statistic for this hypothesis test is
nothing.
​(Round to two decimal places as​ needed.)
Identify the​ P-value for this hypothesis test.
 
The​ P-value for this hypothesis test is
nothing.
​(Round to three decimal places as​ needed.)
Identify the conclusion for this hypothesis test.
 
 
A.
Fail to 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 not
sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to​ 10%.
 
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.
Reject
H0.
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?
 
A. 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 the resturant should work lower the rate.
 
B. since there is not sufficient evidence to reject the cliam that the rate of inaccurate orders is equal to 10 % the resturant should work to lower the rate
 
c. since there is sufficient evidence to reject the claim that the rate of inaccurate orders is equal to 10 % the inaccuracy rate is acceptable
d. since there is sufficent evidence to reject the claim that the rate of inaccurate orders is equal to 10 % the inaccuracy rate is unacceptable, so the resturant should work to lower the rate
