The maximum allowable mean level of a toxin in smelters, herbicide production facilities, and other places where the toxin is used is
0.005
milligrams per cubic meter of air. Suppose smelters at two plants are being investigated to determine whether they are meeting standards. Two analyses of the air are made at each plant, and the results are shown below. A claim is made that the standard is being violated at Plant 2 but not at Plant 1. Do you agree? Assume
α=0.05.
