A study of pollutants showed that certain industrial emissions should not exceed 2.3 parts per million. You believe a particular company may be exceeding this average. To test this supposition, you randomly take a sample of nine air tests. The sample average is 3.3 parts per million, with a sample standard deviation of 0.4. Does this result provide enough evidence for you to conclude that the company is exceeding the safe limit? Use α = 0.05. Assume emissions are normally distributed.
