How is earth's surface most likely to change in a place that experiences strong sand storms?
extensive plant growth will lead to cracks in rocks.
cracks in rocks will deepen due to freezing and thawing.
loosening of soil will occur due to vast network of tunnels.
mechanical weathering will cause wearing away of rocks.

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.
