The chemical trichloroethylene (TCE) is a colorless liquid found in very low concentration in drinking water. The EPA has set a maximum concentration of TCE in drinking water at 5 ppb. Consuming water on a regular basis that contains higher concentrations can lead to cancer. (a) What is the ppb concentration in a 200.0−L (200.0 kg) sample of water that contains 0.15 mg TCE?

What are you drinking? Environmental Protection Agency standards require that the amount of lead in drinking water be less than 15 micrograms per liter. Ten samples of water from a particular source have the following concentrations, in units of micrograms per liter. Assume the population standard deviation is o = 4. If appropriate, perform a hypothesis test to determine whether you can conclude that the mean concentration of lead meets the EPA standards. Use the a-0.01 level of significance and...
