Chapter 1.4, Problem 21BSC

Simple Random Samples. In Exercises 21-26, determine whether the sample is a simple random sample. Give a brief explanation of your choice.

21. Bayer Aspirin Bayer Healthcare LLC produces low-dose aspirin pills designed to contain 81 mg of aspirin. Because each pill contains other ingredients, including corn starch, talc, and propylene glycol, it is difficult to check whether manufactured pills contain 81 mg of aspirin. A quality control plan is to select every 1000th pill, which is then tested for the correct amount of aspirin.
