(5 points) A milk processor monitors the number of bacteria per milliliter in raw milk received at the factory. A random sample of 10 one-milliliter specimens of milk supplied by one producer gives the following data (assume the population is Normal): 5370 4890 5100 4500 5260 5150 4900 4760 4700 4870 Construct and interpret a 90% confidence interval for the population mean μ.

A polluted water sample has 2,400,000 bacteria per ml. You transfer 1.0 ml of sample to a bottle containing 99ml of sterile water. You then take 0.1 ml from this dilution bottle and transfer to a second bottle with 0.9 ml of sterile water. Finally, you transfer 1 ml to a Petri dish with nutrient agar. How many colonies would you expect to find on this plate? Would it be countable?

Suppose you would like to determine the number of bacteria in a culture via an aerobic plate count. Explain (with pictures) how you would set up a dilution series (104, 106, 10) using the fewest number of dilution blanks. Draw and label your tubes and plates with each dilution. Show all volumes including transfers, amounts in tubes, and amounts plated 1. You want to set up a 1:10 dilution series, so that you can plate a 10-1, 102, and a...
