A toy manufacturer produces a product for which there are 10 possible defect opportunities. If in the course of a week the company makes 1,000 units and discovers 17 total defects, which value below most closely corresponds to the manufacturer's sigma level?

First, we need to calculate the defect rate (DR):

DR = Total Defects/Total Opportunities

DR = 17/10,000

DR = 0.0017

Next, we need to calculate the Defects Per Million Opportunities (DPMO):

DPMO = DR * 1,000,000

DPMO = 0.0017 * 1,000,000

DPMO = 1700

Using this DPMO value, we can refer to a sigma level table to find the corresponding sigma level.

According to the table, a DPMO of 1700 corresponds to a sigma level of 4.5. Therefore, the closest value below is C: 4.5.
