In an experiment conducted in the civil engineering department at Virginia Tech, a growth of a certain type of algae in water was observed as a function of time and the dosage of copper added to the water. The data are as follows. Response is in units of algae.(a) Do an analysis of variance and show the analysis of variance table.(b) Comment concerning whether the data are sufficient to show a time effect on algae concentration.(c) Do the same for copper content. Does the level of copper impact algae concentration?(d) Comment on the results of the test for interaction. How is the effect of copper content influenced bytime?
