    2. In investigating the Ideal Gas Law experiments are to be run at four different pressures and three different temperatures.
    a. How many experimental conditions are to be studied?
    b. If each experimental condition is replicated (repeated) 5 times how many experiments will be conducted on a given gas?
    c. How many experiments must be conducted to obtain five replications on each experimental condition for each of six different gases?3. Tests will be run on five different coatings used to protect fiber optics cables from extreme cold. These tests will be conducted in random order.
    a. In how many orders can the tests be run?
    b. If two of the coatings are made by the same manufacturer what is the probability that tests on these coatings will be run back to back?
    c.
    4. The effectiveness of irradiated polymers in the removal of benzene from water is being investigated. Three polymers are to be studied. Each is to be tested at four different temperatures and three different radiation levels.
    a. How many different experimental conditions are under study?
    b. If each experimental condition is to be replicated (repeated) five times how many experiments must be conducted?
