Let P Denote the Proportion of Defective Items in the Lot

Short Answer

Let p denote the proportion of defective items in the lot, and P(A) denote the probability that the lot is accepted. Let us designate two different values of p, one for which P(A) is a specified value close to 1 and the other for which P(A) is a specified value near 0. These tow values of $p - \operatorname { say } p _ { 1 } \text { and } p _ { 2 } -$ are often called the __________, denoted AQL, and the __________, denoted by LTPD.
