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.)

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 37 orders that were not accurate among 336 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 0.62 (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 31 orders that were not accurate among 376 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? The test statistic for this hypothesis test is The P-value for this hypothesis test Identify the conclusion for this hypothesis test.

15. In a study of the accuracy of fast food drive-through orders, McDonald's had 33 orders that were not accurate among 362 orders. Use a 0.05 significance level to test the claim that the rate of inaccurate orders is equal to 10%. a. Null and Alternative Hypotheses. H0: p = 0.10 Ha: p ≠ 0.10 b. Compute the test statistic. z = (ŕ - p0) / √(p0(1 - p0) / n) = (0.091 - 0.10) / √(0.10(1 - 0.10) / 362) = -0.561 c. Compute the p-value. (Choose which probability is appropriate). p - value = 2 * P(Z > 0.561) = 2 * NormCDF(0.561, 999999, 0, 1) = 0.575 d. Write your conclusion in context of this problem. p - value > α so we fail to reject H0 There is not significant evidence to conclude that the rate of inaccurate orders is not equal to 10%.
