In a sample of 7 cars each car was tested for nitrogen-oxide emissions (in grams per mile) and the following results are obtained
0.18, 0.16, 0.08, 0.06,0.17,0.12,0.15 assuming that this sample is representative of the cars in use. cosntruct a 98% confidence interval estimate of the mean amount of nitrogen=oxide emissions for all cars. if the epa requires that nitrogen oxide emissions can be less than 0.165g.mi we can safely conclude that requirement is being met
A)what is the confidence interval estimate of the mean amount of nitrogen-oxide emissions for all cars
___g/mi
