Estimating Car Pollution In a sample of seven cars, each car was tested for nitrogen- oxide emissions (in grams per mile) and the following results were obtained: 0.06, 0.11, 0.16, 0.15, 0.14, 0.08, 0.15 (based on data from the Environmental Protection Agency). Assuming that this sample is representative of the cars in use, construct a 98% confidence interval estimate of the mean amount of nitrogen-oxide emissions for all cars. If the Environmental Protection Agency requires that nitrogen-oxide emis- sions be less than 0.165 grams>mile, can we safely conclude that this requirement is being met?
