I need help with these questions about the problem I am working on 1. Round each of the concentration values to the nearest integer value and write the rounded numbers on the lines provided in the table of Fig. A1.7.1. To get you started, the first rounded value is 316.2. Plot the data onto the graph as carefully as you can.3 Use a ruler to draw a line that follows the trend of the points. To do this, you will need to visually approximate by drawing the line so that it passes through the middle of the points with about as many points above as below the line.
