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 AOL specified by thet depertment

is $21\%$ while the LTPO acceptable by the assembly department is $55\%$ Assume the company is wiling to accept a consumer's risk of to

percent and a proctucer's risk of $5$ percent.

a$.$ Find the sample size. Ust

Nete: if the exact value of the computed LTPO $\frac{+}{{?}_{\frac{?}{?}}}OQ$ ratio foes not appear in Exhlat $1016,$

use the next higher ratio.

Note: Round up your answer to the next whole number.

b$.$ How would you tell someone to do the test?

Randomly sampio LSl using the samplo sico from part a$,$
