The responsibilities of a Black Belt typically include all EXCEPT

A process characteristic follows a normal distribution with a mean of 25.15 and standard deviation of 0.9.  The spec limits for the characteristic are 25.00 +/- 1.5.   If a sample of 9 parts are taken from the process, what is the probability that there will be no parts out of spec in the sample?

If a process is adjusted based on a single sample or data point without regard for common cause variation, this would be known as

If a process is adjusted based on a single sample or data point without regard for common cause variation, this would be known as

Which of the following is not true of cause and effect analysis?

The number of cycles to failure for a system follows a lognormal distribution with parameters µ= 12 and σ = 3.  What is the probability that the system will fail in less than 150 cycles?

Histograms are useful for showing

A bottle of liquid hand soap indicates that it contains 8 oz.  In the process of filling the bottles, it is known that 3% of the bottles are under-filled and do not contain the full 8 oz.  If 5 bottles are randomly selected from the process, what is the probability that none of the bottles are under-filled?

A supplier knowingly places 5 defective circuit boards in a shipment of 25 boards.  At receiving inspection, the customer selects 8 boards at random for inspection.  What is the probability that exactly 2 defective boards will be in the inspection sample?

The number of cycles to failure for a system follows a lognormal distribution with parameters µ= 12 and σ = 3.  What is the probability that the system will fail in less than 150 cycles?
