Final answer:
The question involves a quality control chemist assessing the accuracy and precision of three machines dispensing cough syrup, with accuracy referring to how close the average volume is to 10 ounces, and precision referring to the consistency of the dispensed volumes.
Step-by-step explanation:
The question relates to the accuracy and precision of medication dispensing systems within a healthcare context, specifically through the lens of a quality control chemist at a pharmaceutical company. The task involves assessing three different machines designed to dispense exactly 10 ounces (296 mL) of cough syrup. The chemist fills five bottles using each machine and records the actual volume dispensed. Accuracy here would refer to how close the average dispensed volume is to the intended 10 ounces, while precision would refer to how similar the volumes dispensed by the same machine are across multiple trials.
For example, if one machine dispenses volumes of 296.1 mL, 296.3 mL, 296.2 mL, 296.2 mL, and 296.3 mL, this machine would be considered both accurate and precise as the volumes are close to the target and very similar to each other. In contrast, if another machine dispensed 295.0 mL, 298.0 mL, 297.0 mL, 294.0 mL, and 299.0 mL, this machine would not be considered precise due to the considerable variation in volumes, and its accuracy would require additional analysis to determine how the average of these numbers compares to the desired 296 mL target.
