Suppose we have a process that makes extension cords. The target value for the length of the extension cord is 5 meters. The standard deviation of the process is

0.04 meters. The manufacturer wants the USL to be 5.015 meters, and the LSL to be 4.960 meters. If it costs $0.28 to fix any extension cord that is longer than the USL and

$0.74 to fix anyone shorter than the LSL. It material cost for each meter of the extension cord is $0.13, and the manufacturer produces

120,000extension cords per year.

a) Zdown = (round your response to two decimal places).

b) P (< LSL) =

nothing

(round your response to four decimal places).

c) Zup = (round your response to two decimal places).

d) P (> USL) = (round your response to four decimal place)

e) The annual expected fixing cost of these extension cords is

$ (round your answer to the nearest dollar).

f) The annual expected material cost of these extension cords is $ (round your answer to the nearest dollar)
