The effects of a toxic pollutant upon fish was examined by placing fish in a solution of water with various concentrations of the pollutant. The time (in minutes) until the fish showed distress was recorded at which the fish were removed from the container. A total of 18 different experiments were performed. Note that the pollutant is measured on a logarithmic scale where a change of one unit represents an increase of 10 fold in the pollution concentration. The computer output appears below:

The regression model is:

Solution

The regression model is:

y = 7.5641-1.0269*Logpollut
