Each car in a sample of seven cars was tested for nitrogen-oxide emissions
Each car in a sample of seven cars was tested for nitrogen-oxide emissions
(in grams per mile), and the following results were obtained. 0.08, 0.11,0.15, 0.13, 0.12, 0.05, 0.13. Assuming that this sample is representative of cars in use, construct a 95% confidence interval estimate of the mean amount of nitrogen-oxide emissions for all cars. Round to the nearest thousandth
