Question

An industrial research is developing a new kind of filtration system for use in a home aquarium. The device is designed for nitrogen removal using bacteria grown inside the filter system. The researcher wants to know if the new filter system has different nitrogen removal properties than the current system sold by her company. To test the new filter system, 40 aquaria were divided into two groups, one filtered with the antiquated filtration system (Model 1) and one filtered by her newly developed Model 2 aquarium filter. If the Model 2 filter is more effective it will have a lower N concentration. The nitrogen content of the water in each aquarium is reported in the table below in parts per million N. (Parts per million, or ppm, is the same as mg / L).

Answer 1

The researcher is testing a new filtration system for nitrogen removal in a home aquarium by comparing it to the current system. The nitrogen concentration in the water of each group is measured to determine the effectiveness of the filtration.

Step-by-step explanation:

The researcher is testing a new filtration system for nitrogen removal in a home aquarium. The system is compared to the current one by measuring the nitrogen concentration in the water of each group. Lower nitrogen concentration indicates more effective filtration. The data collected will determine if the new filter system has different nitrogen removal properties than the current system
