You are interested in buying a new car. One of the many points you want to consider is the resale value of the car after 5 years. Since you are particularly interested in a certain foreign sedan, you decide to estimate the resale value of this car with a 90% confidence interval. You were able to get data on 17 5-year-old foreign sedans of the same model that were recently resold. These 17 cars were resold at an average price of $ 12,590 with a standard deviation of $ 800. What is the 90% confidence interval for the true median resale value of a 5-year car of this model?
