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 0.10 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. {'1 A. H0:p=0.1 H1:p 0.20 H, : p = 0.20 O C. Ho: P = 0.20 H1 : p > 0.20 O D. Ho: P = 0.20 Hy : p #0.20 Identity the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Reject Ho. There is sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. O B. Fail to reject Ho. There is sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. O C. Fail to reject Ho. There is not sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. O D. Reject Ho. There is not sufficient evidence to warrant support of the claim that more than 20% of users develop nausea.A certain drug is used to treat asthma. In a clinical trial of the drug, 28 of 252 treated subjects experienced headaches 1-PropZTest (based on data from the manufacturer). The accompanying calculator display shows results from a test of the claim that less than 9% of treated subjects experienced headaches. Use the normal distribution as an approximation to the binomial prop
