Answer 1

The sampling method used in this study is **Stratified Sampling**. In stratified sampling, the population is divided into different subgroups or strata (in this case, by hair color), and samples are then taken from these specific groups. In this example, the researchers are specifically surveying individuals from the "blonde" subgroup, which indicates a stratified approach.
