Assume the company is willing to accept a consumer's risk of 10percent and a producer's risk of 5 percent.a. Find the sample size. Use Exhibit 10.16. Note: If the exact value of the computed LTPD/AOQ ratio does not appear in Exhibit 10.16,use the next higher ratio. (Round up your answer to the next whole number.)Sample sizeb.
