11.0, 0.07, 0.12, 0.19,0.17, 0.17, 0.15 Assuming that this sample is representative of the cars inuse, construct a 98
98% confidence interval estimate of the mean amount ofnitrogen-oxide emissions for all cars. If the EPA requires thatnitrogen-oxide emissions be less than 0.165 g divided by mi
g/mi, can we safely conclude that this requirement is beingmet?
