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. data: 0.5 Wilk-Shapiro Test for Normality data: 1.2 p-value = 0.324 p-value = 0.2534 data: 1.5 p-value = 0.6369 Bartlett test of homogeneity of variances height by carbon dioxide data: Bartlett's K-squared 4.5623, df = 2, p-value = 0.1022 Analysis of Variance Df Sum Sq Mean Sq F value Pr (>F) carbon dioxide 2 88.73 44.37 6.131 0.0289 * Residuals 7 50.65 7.24 .
