2) Listed below are the measured amounts of lead (in micrograms per cubic meter) in the air. The measurements shown below were recorded at Building 5 of the World Trade Center site on different days following Sept 11, 2001. After the collapse of the two World Trade Center buildings, there was considerable concern about the quality of the air. Use a 0.05 significance level to test the claim that the sample is from a population with a mean greater than...
