Question

WMS 5.10) An environmental engineer measures the amount (by weight) of particulate pollution in air samples of a certain volume collected over two smokestacks at a coal-operated power plant. On eof the stacks is equipped with a cleaning device. Let Yi denote the amount of pollutant per sample collected above the stack that has no cleaning device and Y2 denote the amount of pollutant per sample collected above the stack that is equipped with with the cleaning device. Suppose the frequency behaviour of Yi and y2 can be modeled by f(yi,p)=(0, elsewhere
