In a study of the accuracy of fast food drive-through orders, one restaurant had 33 orders that were not accurate among 380 orders observed. Use a 0.10 significance level to test the claim that the rate of inaccurate orders is equal to 10%. Does the accuracy rate appear to be acceptable?

A.
Failtoreject
H0.
There
isnot
sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to 10%.
B.
Reject
H0.
There

D.
Reject
H0.
There
isnot
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
isnot
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 unacceptable, so the restaurant should work to lower that rate.
C.
Since there
isnot
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%.
