In a study of the accuracy of fast food drive-through orders, one restaurant had 38 orders that were not accurate among 325 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? Identify the test statistic for this hypothesis test. Also identify the p value for this hypothesis test. Identify the null and alternative hypotheses for this test.
