Transcribed Image Text:For numbers 24-26: Aquascaping involves growing aquatic plants and
aesthetically arranging them in an aquarium like a natural landscape. Success of
growing plants depends on several factors such as light condition, water pH, and
carbon dioxide level. It is of interest to determine if varying concentrations of
carbon dioxide (0.5 ppm, 1.2 ppm, 1.5 ppm) introduced to an aquarium will
promote or deter an aquatic plants' growth. Ten aquariums with one-week old
plant were set-up and randomly assigned to each treatment. Below are the R
outputs with 5% level of significance.
