## Step 1The problem involves understanding the concepts of population, sample, and data collection methods in statistics. The population in this context refers to all the individuals who are being studied, while the sample is a subset of the population that is selected for the study.## Step 2The problem states that the pollsters are conducting a survey on 2,500 individuals. Therefore, the sample in this case is the 2,500 individuals surveyed.## Step 3The inference of interest to the pollster is to estimate the proportion of all citizens who believe the president is doing a good job. This is because the pollsters are conducting an opinion poll to determine the popularity rating of the current president.## Step 4The method of data collection employed in this case is a survey.
