Final answer:
The nutrient intakes set at a level to meet the requirement for half of the population are called Estimated Average Requirements (EAR) and are used as a basis for setting the Recommended Dietary Allowance (RDA).
Step-by-step explanation:
The nutrient intakes set at a level to meet the requirement for half of the population are called Estimated Average Requirements (EAR). The EAR is the estimated nutrient requirement that meets the needs of 50% of the population. It is used as a basis for setting the Recommended Dietary Allowance (RDA), which is the intake level that is sufficient to meet the nutrient requirements of 97.5% of the population.
For example, if the EAR for vitamin C is determined to be 75 milligrams per day, the RDA would be set at a higher level to ensure that most people in the population meet their vitamin C needs.
