A process that produces computer chips has a mean of .04 defective chip and a standard deviation of .003 chip. The allowable variation is from .037 to .043 defective. |
| a. |
Compute the capability index (Cp) for the process. (Round your intermediate calculations to 3 decimal places and final answer to 2 decimal places.) |

Homework Answers
a. Cp = (Upper Specific Limit - Lower Specific Limit)/6*Standard Deviation
= (0.043 - 0.037)/6*0.003
= 0.33
b. No
The process if not capable because in order to make the process capable it has to be more than 1

Suppose that a computer chip company has just shipped 10,000 computer chips to a computer company.
Suppose that a computer chip company has just shipped 10,000 computer chips to a computer company. Unfortunately, 60 of the chips are defective. (a) Compute the probability that two randomly selected chips are defective using conditional probability. (b) The probability that the first randomly selected chip is defective is 60/10,000 = 0.006 = 0.6%. Compute the probability that two randomly selected chips are defective under the assumption of independent events. (a) The probability is _______ (Round to eight decimal places as needed.)

A manufacturer of computer memory chips produces chips in lots of 1000. If nothing has gone wrong in the manufacturing process, at most 7 chips each lot would be defective, but if something does go wrong, there could be far more defective chips. If something goes wrong with a given lot, they discard the entire lot. It would be prohibitively expensive to test every chip in every lot, so they want to make the decision of whether or not to...
