Alake has water quality as follows: dissolved oxygen, 60; nitrate, 6.10 (mg/l); phosphate, 0.8 (mg/l); and ph, 5.5. answer the following: what is the wqi of this water if the weighting factors of the corresponding water quality parameter are 0.3, 0.2, 0.2, and 0.3, respectively? what is the wqi of this water if the weighting factors of the corresponding water quality parameter are 0.5, 0.2, 0.2, and 0.1, respectively? why are they different? how would one determine the weighting factors of each water quality parameter?

If 1.8 l of water is added to 2.5l of a 7.0 molarity koh solution, what is the molarity of the new solution

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
