MRTH maintains that no more than 10% of trucks on the roads are over-weight and has publically indicated that the percentage is less. As a precaution, MRTH plans to weigh a sample of trucks operating on major routes. Unless the data reject its beliefs, MRTH will continue normal enforcement operations. If the data reject its beliefs, MRTH will institute reforms. Let p denote the proportion of overweight trucks operating on roads. 27. Suppose MRTH decides to test Ho : p 0.135. If p = 0.15, then (assume the usual conditions are met) the probability that MRTH fails to reject Ho is (A) 0.025 (B) 0.20 (C) 0.05 (D) 0.67 (E) None of the above. 30. An analyst dislikes hypothesis testing and produced a 95% confidence interval from the data, with the interval found to be 0.093 to 0.157. Based on this confidence interval (assuming the usual conditions), MRTH should (A) Fail to Reject Ho : p = 0.10 (B) Reject Ho : p # 0.10 (C) Use a 90% confidence interval instead. (D) Gather more data until the confidence interval omits 0.10. (E) None of the above. + 10
