Question

A group of concerned citizens are collecting water samples from a local river to detect the level of nitrogen in the water. They plan to take samples every day for a month and then will divide the sum by the number of days they sampled. What is the group trying to do?

Answer 1

Answer:Estimating the average level of nitrogen in the water

Step-by-step explanation:

The concerned citizens are trying to determine the average level of nitrogen in the water. They collected the samples for a month in order to get the correct average reading of nitrogen.

They might be interested in knowing whether there is excess nitrogen in water or not as excess nitrogen can overstimulate the growth of aquatic plant and algae. Excess growth can, in turn, clog water intakes, use dissolved oxygen, Block sunlight by covering the entire lake.
