You Are Interested in Purchasing a New Car

question 41

Multiple Choice

You are interested in purchasing a new car. One of the many points you wish 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 manage to obtain data on 17 recently resold 5-year-old foreign sedans of the same model. These 17 cars were resold at an average price of $12,630 with a standard deviation of $800. Suppose that the interval is calculated to be ($12,291.23, $12,968.77) . How could we alter the sample size and the confidence coefficient in order to guarantee a decrease in the width of the interval?

• A) Decrease the sample size but increase the confidence coefficient.
• B) Increase the sample size and increase the confidence coefficient.
• C) Keep the sample size the same but increase the confidence coefficient.
