Assume statistical independence between the concentration

Reference no: EM13555190

The daily concentration in the air for a given city is normally distributed with a mean of 0.03ppm and c.o.v. of 40%. Assume statistical independence between the concentration for any two days. Suppose the criteria for clean air standard require that:

1. The weekly average concentration should not exceed 0.04ppm.

2. The concentration should not exceed 0.075ppm on more than one day during a given week.
