A supplier contract calls for a key dimension of a part to be between 1.96 and 2.04 centimeters. The supplier has determined that the standard deviation of its process, which is
- If the actual
mean of the process is 1.98, what fraction of parts will meet specifications? - If the mean is adjusted to 2.00, what fraction of parts will meet specifications?
- How small must the standard deviation be to ensure that no more than 2% of parts are nonconforming, assuming the mean is 2. 00?
