A researcher developing scanners to search for hidden weapons at airports has failed to conclude that a new scanner is significantly better than the current scanner. He made his decision based on a test using a = 0.025. Would he have made the same decision at a = 0.20? How about a = 0.01? Explain. Select the statement relating decision making to values of a. O A. His decision may have been different for a = 0.01 but would have been the same for a = 0.20. O B. His decision would have been the same for both a = 0.01 and a = 0.20. O C. His decision may have been different for a = 0.20 but would have been the same for a = 0.01. D. His decision may have been different for both a = 0.01 and a = 0.20
