The Asian long-horned beetle can infect a variety of tress such as maple trees and elm trees. These beetles eat the inside
infected tree and destroy the pathways that water and nutrients travel through to get from the roots to the rest of the tree. This
results in the tree becoming sick and eventually dying.
A cargo ship carrying Asian long-horned beetles introduces the species into a region where the beetles were not previously present.
This region has a diverse population of maple and elm trees. How will humans in the area likely be impacted?
OA. The maple syrup industry will be negatively impacted due to a decrease in the maple population.
OB. The housing industry will be negatively impacted due to an increase in lumber costs.
OC. The lumber industry will be negatively impacted due to a decrease in available resources.
OD. all of these

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.
