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. O A. Ho:p=0.1 H:p0.1 OC. Ho: p#0.1 H,:p=0.1 O D. Ho: p=0.1 H,:p#0.1 Identify the test statistic for this hypothesis test.
