Please help answer the following question, thank you.

The data in the le Used HondaCivics come from a sample of used Honda Civics listed for sale online in July 2006. The variables recorded are the car's age (calculated as 2006 minus year of manufacture) and price. We want to determine whether the sample data provide strong evidence of an association between a car's price and age in the population in terms of the population slope. Determine a theory-based 95% confidence interval for the population slope. Round to two decimal places. I I > eTextbook and Media
