In a study of the accuracy of fast food drive-through orders, one restaurant had 40 orders that were not accurate among 321 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?

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 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. D. 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%.

Question

In a study of the accuracy of fast food drive-through orders, one restaurant had

orders that were not accurate among

321

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.

H0:

p≠0.1

H1:

p=0.1

H0:

p=0.1

H1:

p<0.1

H0:

p=0.1

H1:

p≠0.1

H0:

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.

Reject

H0.

There

is not

sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to 10%.

Reject

H0.

There

sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to 10%.

Fail to reject

H0.

There

sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to 10%.

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?

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.

Since there

sufficient evidence to reject the claim that the rate of inaccurate orders is equal to 10%, the inaccuracy rate is acceptable.

Since there

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.

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

10%.

This rate would be too high,

so the restaurant should work to lower the rate.
