Small or even large mountainous areas that have had long droughts or who have had many wildfires are prone to mudslides because many plants are destroyed during those processes. Mudslides are when large amounts of water accumulate rapidly in the soil in mountainous areas. The soil becomes over saturated with water and gravity causes the water-soaked soil to “run down” the mountain in a river like behavior. Without plants and their root systems to hold the soil in place, the soil gets washed away during rail storms. Which natural process causes these mudslides and washes away the soil?

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.
