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.) Machine Cost per Unit (5) Standard Deviation (mm) .057 .860 We can narrow the choices to processes Click to select) < Prex 38 of 40 # Next > ere to search

Answer 1

Cp = Specification width/(6*standard deviation)

Processes Cp values are:

A = 0.48/(6*0.057) = 1.404

B = 0.48/(6*0.060) = 1.333

C = 0.48/(6*0.063) = 1.270

D = 0.48/(6*0.064) = 1.250

So, we can narrow choice to Process A although the cost is highest
