Suppose your manager presents you with the following information about machines that could be
used for a job, and wants your recommendation on which one to choose. The specification width
is .48 mm. In this instance, you can narrow the set of choices, but you probably wouldn’t make a
recommendation without an additional piece of information. (Round your answers to 3 decimal
places.)
