Question 521 pts Following is an ergonomic problem which involves the use of anthropometric data that you received in your packet of materials at the beginning of the semester: You are the supervisor of an appliance manufacturing firm that is designing an electrical harness assembly line. An individual from your engineering department wants to install fixed-height workbenches for standing employees at a height which accommodates only the 50th percentile of the population (i.e., approximately 40" high). Having a basic understanding of ergonomic as well as anthropometric principles, you push for the workbenches to possess adjustability from a height standpoint. The engineer then wants to know the lowest as well as highest distances from the floor (in inches) that the workbench height should be able to attain. Given your understanding of anthropometrics as well as the preferred vertical distance that a workbench should be from the palms of a pronated hand to the top of the bench for light assembly work (while the elbow angle is at 90o), what are the lowest and highest distances from the floor that the top of the workbench should be able to attain so as to accommodate the middle 95th percentile of the population (considering all of the employees are wearing 1-inch heels and stand on 1-inch floor mats)? Group of answer choices 38.6 to 42.0 inches 31.8 to 41.3 inches 34.2 to 44.3 inches 45.2 to 45.3 inches 37.2 to 47.3 inches
