3. Researchers are investigating the effectiveness of using a fungus to control the spread of an
insect that destroys trees. The researchers will create four different concentrations of fungus
mixtures: 0 milliliters per liter (ml/L), 1.25 ml/L, 2.5 ml/L, and 3.75 ml/L. An equal number of the
insects will be placed into 20 individual containers. The group of insects in each container will
be sprayed with one of the four mixtures, and the researchers will record the number of insects
that are still alive in each container one week after spraying.
(a) Identify the treatments, experimental units, and response variable of the experiment.
Treatments:
Experimental units:
Response variable: I
(b) Does the experiment have a control group? Explain your answer.
