Question

Ergonomics is the science of making sure that human surroundings are adapted to human needs. How could statistics play a role in the following: Choosing the height of an office chair so that 95 percent of the employees (male and female) will feel it is the "right height" for their legs to reach the floor comfortably. Designing a drill press so its controls can be reached and its forces operated by an "average employee." Defining a doorway width so that a "typical" wheelchair can pass through without coming closer than 6 inches from either side. Setting the width of a parking space to accommodate 95 percent of all vehicles at your local Walmart. Choosing a font size so that a highway sign can be read in daylight at 100 meters by 95 percent of all drivers. All of these involve taking samples from the population of interest and estimating the value of the variable of interest. All of these require the designer to take a census of the population that will be using the chair, drill press, doorway, parking space, or highway signs, in order to ensure 100 percent are accommodated. None of these responses. All of these product specifications could be determined by a smart engineer or designer who represents the "typical" person using each of the products.

All of these involve taking samples from the population of interest and estimating the value of the variable of interest.
