The environmental Protection Agency releases figures on urban air soot in selected cities in the United States. For
the city of St. Louis, the EPA claims that the average number of micrograms of suspended particles per cubic meter
of air is 82. Suppose St. Louis officials have been working with businesses, commuters, and industries to reduce this
figure. These city officials hire an environmental company to take random measures of air soot over a period of
several weeks. The resulting data follow. Use these data to determine whether the urban air soot in St. Louis is
significantly lower than it was when the EPA conducted its measurements. Let a=.05.
