A major car manufacturer wants to test a new engine to determine whether it meets air pollution standards. The mean emission levels of all engines must be not more than 60 parts per million (ppm) of carbon. 10 engines are manufactured for test and the sample mean and standard deviation are 61.1 ppm and 3.0 ppm respectively. Do these data provide sufficient evidence to conclude that this engine does not meet the pollution standards? Using 5% level of significance.
