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 $ 12 comma 100 with a standard deviation of $ 800. What is the 95% confidence interval for the true mean resale value of a 5-year-old car of this model?

Standard deviation of the sample (S) = 800

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

Step(ii):-

Degrees of freedom ν =n-1 = 17-1 =16

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

(12,100 - 411.32 , 12,100 + 411.32)

(11,688.68 , 12,511.32)
