The EPA has stipulated that the Pollution Standard Index (PSI) for clean air standards is to average no more than 100. A random sample of 9 days for the city of Acme showed PSI readings of 144, 85, 90, 120, 150, 105, 93, 130, and 115.Assume the population of PSI readings is highly nonnormal. The EPA wants to determine if there is significant evidence to conclude that Acme air is dirtier than the stipulated clean air standards. The test is conducted at ? = .05 and the p value is found to be .254. Based on this result, provide a one-sentence managerial conclusion.
