The acceptance line is: da = - 1.084 + (0.032)n — sequential sampling plan used desirable have producer's risk AQL 008 and consumer's

A sequential sampling plan is to be used. It is desirable to have a producer's risk of 0.05 at AQL = 0.008 and a consumer's risk of 0.07 at LQL = 0.082. Determine the equations for the acceptance and rejection lines. What is the first opportunity to reject? What is the first opportunity to accept?

SOLUTION

It is given that a = 0.05, p1 = 0.008, ß = 0.07, and p2 = 0.082. The parameters of the acceptance and rejection lines are calculated as follows:
