You are interested in purchasing a new car. One of the many factors you wish to consider is the resale value of the car after 5 yr of ownership. Since you are primarily interested in the Toyota Camry, you decide to estimate the resale value of the Camry with a 90% confidence interval. You manage to obtain data on 17 recently resold 5-yr-old Camrys and derive a 90% confidence interval that is equal to ($10,400, $14,400). How could we alter the sample size and confidence coefficient in order to decrease the width of this confidence interval?
