In a study of the accuracy of fast food drive-through orders, one restaurant had 30 orders that were not accurate among 385 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. O A. Ho: p=0.1 H1:p>0.1 O B. Ho: p=0.1 H:p<0.1 OC. Ho: p 0.1 H1:p=0.1 D.
