Large$-$scale integrated $($LSI$)$ circuit chips are made in one department of an electronics firm. These chips are incorporated into analog devices that are then encased in epoxy. The yield is not particularly good for LSI manufacture, so the AQL specified by that department is $8\%$ while the LTPD acceptable by the assembly department is $22\%.$ Assume the company is willing to accept a consumer's risk of $10$ percent and a producer's risk of $5$ percent.

Find the sample size. Use Exhibit $13\mathrm{.}10.$ Note: If the exact value of the computed LTPD$/$AQL ratio does not appear in Exhibit $13\mathrm{.}10,$ use the next higher ratio.

How would you tell someone to do the test?
