Question

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

orders that were not accurate among

319

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.

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%.

Does the accuracy rate appear to be 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,

the restaurant should work to lower the rate.

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 higher 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
