Assuming that this sample is representative of the cars in use and that the sample is drawn from a normal​ population, construct a 95​%confidence interval of the mean amount of​ nitrogen-oxide emissions for all cars.​ (Note that x=0.129 and s=0.041​.) The 95​% confidence interval for the mean amount of​ nitrogen-oxide emissions for all cars is enter your response here g/mi to enter your response here g/mi. ​(Round to three decimal places as​ needed.)
