+. A nuclear power facility produces a vast amount of heat, which is usually discharged into aquatic systems. This heat raises the temperature of the aquatic system, resulting in a greater concentration of chlorophyll a, which in turn extends the growing season. To study this effect, water samples were collected monthly at 3 stations for a period of 12 months. Station A is located closest to a potential heated water discharge, station C is located farthest away from the discharge, and station B is located halfway between stations A and C. The following concentrations of chlorophyll a were recorded. Station Month A B January February March 9.867 3.723 4.410 8.416 11.100 14.035 10.700 20.723 13.853 4.470 April May June 7.067 11.670 9.168 8.010 4.778 34.080 9.145 8.990 July August September October 7.357 8.463 3.350 3.358 4.086 4.500 4.210 4.233 6.830 3.630 2.320 5.800 November December 2.953 3.480 3.843 3.610 2.640 3.020 Perform an analysis of variance and test the hypothesis, at the 0.05 level of significance, that there is no difference in the mean concentrations of chlorophyll a at the 3 stations.
