The level of nitrogen oxides measured in grams per mile in the exhaust of cars of a particular model follows a normal distribution: X~N (0.25, 0.05). Government regulations call for NOx emissions to be no higher than 0.3g/mi. Suppose that a sample of 9 cars of this particular model are chosen at random from the production line. State the distribution of the sample mean for this problem
