2    Choose Create a sampling plan.

3    In Measurement type, choose either Go / no go (defective) or Number of defects depending on whether you are tracking defective units or defects per unit.

4    In Units for quality levels, choose one of the unit types depending on your specific measurement.

5    In both Acceptable quality level (AQL) and Rejectable quality level (RQL or LTPD), enter a value to specify the quality levels of the product. Use the same units as you indicated above. For example, use 2 for percent defective and 0.02 for proportion defective.

6    In Producer's risk (Alpha) and Consumer's risk (Beta), enter a value between 0 and 1or use Minitab's default.

7    In Lot size, enter the number of units that you are sampling from. The lot size is not required if the AQL, RQL, and alpha and beta risks are given; however, Minitab requires the lot size to calculate the AOQ curve and the ATI curve.
