![# Manufacturing Shaft Diameter Analysis
A particular manufacturing design requires a shaft with a diameter of 21.000 mm, but shafts with diameters between 20.991 mm and 21.009 mm are acceptable. The manufacturing process yields shafts with diameters normally distributed, with a mean of 21.002 mm and a standard deviation of 0.006 mm.
### Analysis:
#### a. Proportion of Shafts within 20.991 mm and 21.000 mm
The proportion of shafts with diameters between 20.991 mm and 21.000 mm is **0.3371**.
*(Rounded to four decimal places as needed.)*
#### b. Probability of an Acceptable Shaft
The probability that a shaft is acceptable (diameter between 20.991 mm and 21.009 mm) is **0.8449**.
*(Rounded to four decimal places as needed.)*
#### c. Diameter Exceeded by Only 0.5% of Shafts
The diameter that will be exceeded by only 0.5% of the shafts is determined but not specified in the given text.
*(Rounded to four decimal places as needed.)*](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F108f85ec-5786-44dd-b590-51bf325bef20%2F5add9ece-2603-429e-9da5-8060c274c381%2F5umc0vd_processed.jpeg&w=3840&q=75)
