Yоu аre interested in purchаsing а new car. One оf the many pоints you wish to consider is the resale value of the car after 5 years of ownership. Since you are particulary 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 16 recently resold 5-year-old foreign sedans of that model. These 16 cars were resold at an average price of $10,000 with a standard deviation of $1,500. You estimate the true population mean for the resale value of this model of foreign car using a 90% confidence interval. What assumption must be met in order for the confidence interval that you constructed to be valid?
