A summary of the data is below. (The measures are given in parts per million, ppm.) d = X2021 - X2016 d = 0.04 ppm Sa = 0.11 ppm n = 30 sing this summary of the data, test the claim that the average amount of carbon monoxide in Raleigh air in 20 ferent than it was in 2016. Use a level of significance of 0.01. full credit, you must show all work including the hypotheses with the claim labeled, a sketch or descripti sampling distribution indicating the direction of the test, the test statistic, and the P-value.
