Question

n a study of the accuracy of fast food​ drive-through orders, one restaurant had 33 orders that were not accurate among 361 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? Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. Upper H 0H0​: pnot equals≠0.10.1 Upper H 1H1​: pequals=0.10.1 B. Upper H 0H0​: pequals=0.10.1 Upper H 1H1​: pgreater than>0.10.1 C. Upper H 0H0​: pequals=0.10.1 Upper H 1H1​: pless than<0.10.1 D. Upper H 0H0​: pequals=0.10.1 Upper H 1H1​: pnot equals≠0.10.1 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 rejectFail to reject Upper H 0H0. There isis sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to​ 10%. B. RejectReject Upper H 0H0. There is notis not sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to​ 10%. C. RejectReject Upper H 0H0. There isis sufficient evidence to warrant rejection of the claim that the rate of inaccurate orders is equal to​ 10%. D. Fail to rejectFail to reject Upper H 0H0. There is notis 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 isis sufficient evidence to reject the claim that the rate of inaccurate orders is equal to​ 10%, the inaccuracy rate is acceptable. B. Since there isis 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 is notis not sufficient evidence to reject the claim that the rate of inaccurate orders is equal to​ 10%, it is plausible that the inaccuracy rate isis ​10%. This rate would be too highThis rate would be too high​, the restaurant should work to lower the rate.the restaurant should work to lower the rate. D. Since there is notis 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. Click to select your answer(s).

Answer 1

Conclusion -> 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%, it is plausible that the inaccuracy rate is ​10%. This rate would be too high​, the restaurant should work to lower the rate.
