Final answer:
The statement regarding the objective of QA/QC being to do the job correctly the first time is True. Accuracy means how close a measurement is to the standard value, while precision reflects how repeatable the measurements are. Human experiments are possible with ethical clearance, and larger sample sizes are preferred for reliability in scientific experiments.
Step-by-step explanation:
The statement that one of the objectives of QA/QC is doing the job correctly the first time is True. Quality Assurance (QA) and Quality Control (QC) are both parts of quality management focused on providing confidence that quality requirements will be fulfilled.
The aim of QA/QC is to prevent defects by focusing on the process used to create the product or service, with the goal being to get things right on the first attempt, thus enhancing efficiency, reducing waste, and saving time.
Accuracy and precision are critical concepts in QA/QC. Accuracy refers to the closeness of a measured value to a standard or known value, while precision refers to the closeness of two or more measurements to each other. Precise values can be consistently reproduced, which is highly valued in quality management.
Concerning the statement about experiments on humans, it is False. Experiments can be done on humans, but they must adhere to strict ethical guidelines. As for the statement regarding sample sizes in scientific experiments, it is True that larger sample sizes are generally better than smaller ones because they tend to provide more reliable and generalizable results.
Therefore, the statement 'One of the objectives of QA/QC is doing the job correctly the first time' is True.
