Final answer:
The stratified quota sampling method will produce projectable results by dividing the population into strata and setting quotas within each stratum to ensure representation.
Step-by-step explanation:
In this question, the sampling method that will produce projectable results is the stratified quota method.
The stratified quota method involves dividing the population into strata or groups based on certain characteristics. Then, within each stratum, a quota is set to ensure that a representative sample is chosen. This method allows for projectable results because it ensures that each stratum is properly represented in the sample.
For example, in part a of the exercise, the soccer coach selects players from different age groups to form a recreational soccer team. By selecting players from each age group in a specific quota, the coach ensures that the sample is representative of the entire population in terms of age.
