2 point If you changed the volume of a sample of gas from 1.5 L to 3.5 L, would
you expect the pressure to increase or decrease?
increase, because the variables are inversely related.
increase, because the variables are directly related.
decrease, because the variables are inversely related.
decrease, because the variables are directly related.

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.
