The true mean weight of the residents in the town can be estimated by taking the mean weight and applying the margin of error. With a mean weight of 173 pounds and a margin of error of 7 pounds, the reasonable range for the true mean weight would be between 166 pounds and 180 pounds. This means the true mean weight likely falls somewhere within this interval. Understanding margins of error is critical in various fields, such as polling and medical studies. It helps communicate the reliability of estimates and shows how sample data may vary from their true population parameters. So, when interpreting survey results, always look for the margin of error to gauge confidence in the findings!
