In a study of the accuracy of fast food​ drive-through orders, one restaurant had 36 orders that were not accurate among 302 orders observed. Use a 0.10 significance level to test the claim that the rate of inaccurate orders is equal to​ 10%. 1. Does the accuracy rate appear to be​ acceptable? 2. Identify the null and alternative hypotheses for this test. 3. What is the test statistic for this hypothesis test? 4. What is the P-Value for this hypothesis test? 5. Reject or Fail to Reject?

Solutions

Expert Solution

Let p denotes the true rate of inaccurate orders.

So, we can say that the accuracy rate appears to be​ acceptable.
