Abstract

A dissolved oxygen sensor tests the amount of dissolved oxygen, in an amount of water. The purpose of this is to show the impact of pollution on water quality. It was hypothesized if alkaline water was polluted with motor oil than the amount of dissolved oxygen present in the water would decrease more than if the water was polluted with diesel fuel. In the current experiment the water was tested with 80 to 100 concentration of an oil to water 32 times for each type of oil. The amount of dissolved oxygen produced was recorded before and after the water was polluted and the measurements were calculated. The independent variables were the type of oil and the dependent was the amount of dissolved oxygen left after the oils were added. The ANOVA test was done with an a=0.05 while H0=m1=m2=m3; H0= there is a significant difference between the variables (claim). Because the p value was below the a=0.05 A Tukey post hoc test had to be constructed. The F-equation was found to be F(3,124)=588.38, p< 0. There was a difference among all the means, because the confidence intervals did not contain zero. There was a significant difference between all of the means compared to the control and with each other.
