QUESTION 2 Problems 2-5 A methods and measurements analyst needs to develop a time standard for a certain task. The task involves the use of a ruler and portable electric saw to mark and cut. In a preliminary study, he observed one of his workers perform this task five times. The observations were made in an air-conditioned, well-lighted training facility, at ground level, with all tools and equipment clean and readily available. Observation: 1 2 3 4 5 Task time (seconds): 82 74 80 83 76 What is the actual cycle time for this task? 82 seconds 74 seconds 80 seconds 79 seconds QUESTION 3 What is the normal time for this task if the employee worked at a 15% faster pace than is typical for adequately trained workers? 90.85 seconds 100.95 seconds 77.95 seconds 95.85 seconds QUESTION 4 What is the standard time for this task if allowances are 7% constant and 4% variable? (British convention) 90.85 seconds 100.95 seconds 102.1 seconds 95.85 seconds QUESTION 5 If the analyst then thought more carefully about his experiment and decided that the variable allowances needed to be increased to match the real (outside, un-air-conditioned) work environment, and that the proper variable allowance was not 4% but 9%, what is the revised standard time? (British convention) 90.85 seconds 100.95 seconds 102.1 seconds 108.2 seconds
