In a sample of seven cars, each car was tested for nitrogen-oxide emissions(in grams per mile) and the following results were obtained: 0.18, 0.08, 0.17, 0.13, 0.07, 0.06, 0.08. 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 EPA requires that nitrogen-oxide emissions be less than 0.165 g/mi, can we safely conclude that this requirement is being met?
