down to submit your answers A production line manufactures basic electronic
parts. If an electronic part does not work, it will be considered as one defect
and scrapped. A simple random sample of 12,000 parts is tested to assess the
production line. Fifty four defects were found. In answering the following
questions, you would need to use the specified number of decimal places. In
addition, to calculate the sigma level, you can use Excel by typing in
=Norm.S.INV(1-DPU)+1.5 where DPU is the value you get earlier. And, to
calculate the number of expected defects, you need to rely on the lookup table
below.

(a)[6] What is the DPU
of the production line? (use 7 decimal places if applicable)

(b)[4] What is the
corresponding DPMO? (use 1 decimal place if applicable)

(c)[6] What is the sigma
level? (use 2 decimal places)

(d)[4] For a sigma level
of 3.0, what would be the number of defects? (use 2 decimal places)

Sigma Level 2.0 3.0 4.0
5.0 6.0

DPMO 308,537.5 66,807.2
6,209.7 232.6 3.4
