Final answer:
A sample survey obtains data from a subset of a population to evaluate traits of the population. The correct answer is:d) A sample survey
Step-by-step explanation:
The correct option that obtains data from a subset of a population to evaluate traits of the population is d) A sample survey. A sample survey involves selecting a smaller group, or sample, from a larger population and collecting data from that sample. This method is often used when it is not feasible or practical to collect data from the entire population. A sample survey obtains data from a subset (sample) of a population to make inferences about the entire population. It involves collecting information from a representative group, and the findings are then generalized to the larger population. This method is commonly used in various fields to study characteristics, opinions, and behaviors of populations without having to examine every individual in the entire population.
