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 95% 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 $13,800 with a standard deviation of $600.

  • a. Create a 95% confidence interval for the true mean resale value of a 5-year-old car of that model.

  • b. Interpret the 95% confidence interval obtained in part a.

  • c. What assumption is required for the interval, part a, to be valid?


Suppose you wanted to estimate a binomial proportion, p, correct to within 0.03 with probability 0.90. What size sample would need to be selected if p is known to be approximately 0.65?
