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.)

Question
In a sample of seven​ cars, each car was tested for​ nitrogen-oxide emissions​ (in grams per​ mile) and the following results were​ obtained:
0.14​, 0.13​, 0.18​, 0.17​, 0.11​, 0.06​, 0.11.
 
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.
