In a study of the accuracy of fast food drive-through orders, one restaurant had 33 orders that were not accurate among 400 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. The test statistic for this hypothesis test is The P-value for this hypothesis test is Identify the conclusion for this hypothesis test.

Step 1
The null hypothesis (H0) is that the rate of inaccurate orders is equal to 10%. In other words, H0: p = 0.10. The alternative hypothesis (H1) is that the rate of inaccurate orders is not equal to 10%. In other words, H1: p ≠ 0.10. Show more…

In a study of the accuracy of fast food drive-through orders, one restaurant had 39 orders that were not accurate among 341 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. 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.)

In a study of the accuracy of fast food drive-through orders, one restaurant had 36 orders that were not accurate among 317 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, test statistic, P-value, conclusion, accuracy rate.
