3. The specifications for a critical characteristic of an electric resistor call for it to have a resistance of 500 25 ohms. The process for making the resistors produces a normal distribution of measurements of resistance with a standard deviation of 5 ohms.

a. Calculate C, for this situation.

b. Is the process capable of performing the operation successfully?

c. How far can the process mean deviate from the target value before the process will begin making 1 percent defectives with regard to this characteristic?
