Question 1:

Based on Table 1, which component of surface soil is most accurately measured by Store A, relative to the laboratory results?

Question 2:

The data from which of the testing procedures supports the conclusion that the concentration of phosphorus increases as the depth of the soil tested increases?

Question 3:

Is the conclusion that Store A is more accurate at measuring ammonia concentration than Store B supported by the data in Table 1?

Question 4:

Soil was sampled from an unknown depth and tested by Store A. The concentrations of the soil compounds tested were as follows: Nitrogen = 5.1; Carbon = 24.8; Ammonia = 0.63. According to the data in the table, one would predict that the soil was most likely sampled from a depth of

Question 5:

Which of the following graphs best represents the relationship between the depth of soil and the concentration of carbon, as measured by Store A?
