A Methods and Measurements Analyst needs to develop a time standard for a certain task. The task involves use 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.

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 allowances sum to 14%?
d. If the analyst then thought more carefully about his experiment and decided that the allowances needed to be increased to match the real (outside, not air-conditioned)…
