A Methods and Measurements Analyst needs to develop a time standard for a certain task. The task involves une of a ruler, square, and portable electric saw to mark and cut the notch" in a rafter (a standard carpentry task of home construction). In a preliminary study, he observed one of his workers performing this task five times. The observations were made in an air-conditioned, well-lit training facility, at ground level, with all tools and equipment clean and readily available. 3 4 5 Observation 1 Task time (seconds): 82 2 74 80 83 76 a. What is the actual average time for this task? b. What is the normal time for this task if the employee worked at a 20% faster pace than is typical for adequately trained workers? c What is standard time for this task if rest allowances sum to 14%? d. How many samples should you make should the Analyst want an accuracy within 36%, a confidence level of 95.45%, and given the sample has a standard deviation of 11.65 seconds
