![**Quality Control Exercise**
In this exercise, a manager claims that his process is highly effective. Out of 1,450 manufactured parts, 1,433 were produced without defects and passed inspection.
**Tasks:**
a. **Calculate the Defects Per Million Opportunities (DPMO).**
- Formula: \((\text{Number of Defects} \div \text{Total Opportunities}) \times 1,000,000\)
- Input the result in the box provided, rounding your answer to the nearest whole number.
**Defects per million opportunities:** [ ]
b. **Calculate the Defective Rate.**
- Formula: \((\text{Number of Defects} \div \text{Total Parts}) \times 100\)
- Input the result in the box provided, rounding your answer to three decimal places.
**Defective rate:** [ ] %
c. **Evaluate the Performance Based on Six-Sigma Theory.**
- Choose one option based on the calculated performance.
- Options:
- Not so good
- Good
This exercise is designed to assess your understanding of quality control metrics and how they are used to evaluate manufacturing processes. Calculate carefully and choose the correct evaluation based on Six-Sigma standards.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4075dd7b-7cf0-4080-a9ab-c20ff4793850%2F62551f39-78dc-4010-a4be-b6add626e634%2Fr1r6fwm_processed.png&w=3840&q=75)
