The city manager's statement is an example of statistical inference because they used a sample of 200 homes to make an inference about the entire population of 2,000 homes. It is not a census because they did not inspect all 2,000 homes, and it is not an experiment because they did not manipulate any variables or compare groups. It falls under the category of data and statistics, but the specific type of statistical analysis being used is inference.
