Each car in a sample of seven cars was tested for nitrogen-oxide emissions (in grams per mile), and the following results were obtained. 0.07 0.12 0.16 0.17 0.16 0.07 0.17 a. 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. b.One agency requires that nitrogen-oxide emissions be less than 0.181 gram/ mile. Someone claims that nitrogen-oxide emissions have a mean equal to 0.181 gram/mile. Does the confidence interval suggest that this claim is not valid?
