Q: For the double sampling plan N = 2000, n1=80

For the double sampling plan N = 2000, n1=80, c1= 1, r1=3, n2= 100, c2=2, r2= 3, construct and interpret the ASN curve. Suppose that process average nonconforming rate is 1.5%. Would you prefer the st...

Q: For the double sampling plan N= 2200, n1= 60

For the double sampling plan N= 2200, n1= 60, c1=1, r1=5, n2= 120, c2= 4, r2=5, construct the ASN curve. Within what range of proportion nonconforming values would you prefer the stated double samplin...

Q: Find an expression for the probability of the union of three events

Find an expression for the probability of the union of three events that are mutually independent of each other.

Q: A manufacturer is considering replacement of an existing machine that performs an

A manufacturer is considering replacement of an existing machine that performs an operation on a part. The variable costs are $0.38 per piece on the existing machine and $0.05 per piece on the new mac...

Q: Determine the single sampling plans that will reject lots that are 1

Determine the single sampling plans that will reject lots that are 1.3% nonconforming 8% of the time. Use acceptance numbers of 1, 3, and 5. From a consumer’s point of view, which of these three plans...

Q: Determine the single sampling plans that will accept lots that are 6

Determine the single sampling plans that will accept lots that are 6% nonconforming 12% of the time. Use acceptance numbers of 1, 2, and 4. From a producer’s point of view, which of these plans would...

Q: Determine single sampling plans that will accept lots that are 0.

Determine single sampling plans that will accept lots that are 0.8% nonconforming with a probability of 0.96. Use acceptance numbers of 1, 3, and 4. If we desire batches that are 5% nonconforming to b...

Q: A sampling plan is desired to have a producer’s risk of 0

A sampling plan is desired to have a producer’s risk of 0.05 at AQL =0.9% and a consumer’s risk of 0.10 at LQL =6.5% nonconforming. Find the single sampling plan that meets the consumer’s stipulation...

Q: A sampling plan is desired to have a producer’s risk of 0

A sampling plan is desired to have a producer’s risk of 0.05 at AQL =1.3% nonconforming and a consumer’s risk of 0.10 at LQL= 7.1% nonconforming. Find the single sampling plan that meets the producer’...

Q: A sampling plan is desired to have a producer’s risk of 0

A sampling plan is desired to have a producer’s risk of 0.05 at AQL =2.0% nonconforming and a consumer’s risk of 0.10 at LQL =7% nonconforming. Find the single sampling plan with the largest sample si...
