Ascientist estimates that the mean nitrogen dioxide level in a city is greater than 31 parts per billion. To test this estimate, you a determine the nitrogen dioxide levels for 31 randomly selected days. The results (in parts per billion) are listed to the right. 16 14 28 18 21 31 3335 36 40 42 Assume that the population standard deviation is 10. At = 0.03, can you support the scientist's estimate?
