AP Chemistry: Chapter 1-3 Note Outline

Sx is the standard deviation. Example: Commercial Tylenol contains approximately 500 mg of acetaminophen. A batch of tablets must contain between 450 – 550 mg of acetaminophen per tablet. Suppose a chemical analysis gave the following results for a batch of tablets: 428 mg, 479 mg, 442 mg, and 435 mg. Calculate the standard deviation. ................
