In a study of the accuracy of fast food drive-through orders, one restaurant had 30 orders that were not accurate among 400 orders observed. Use a 0.05 signicance 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. Ho: p = 0.1 H1 : p 0.1 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is El. (Round to two decimal places as needed.)
