Gaussian Distribution:Rejecting Resistors from a Batch
Not what you're looking for?
Question: Commercial resistors of 2% accuracy have a range of values with a standard deviation of 2% nominal resistance. If a particular application requires a resistor value of 1000+/- 40 ohms, how many 2% resistors will be rejected out of a batch of 1000?

Solution Summary
This solution illustrates how for the given type of resistor, an estimation can be made regarding the number of resistors which can be rejected to fulfill a requirement. All calculations are included.
Solution Preview
40 ohm is of 1000 ohm = (40/1000)*100 = 4% == 2 Standard deviation.
Hence, requirement is of resistors ...

- " In question 2, you incorrectly add in the $3.00 dividend that was just paid to determine the value of the stock price using the dividend discount model. In question 4 response, it should have also been recognized that dividend discount models are not useful if any of the parameters used in the model are inaccurate. "
