Step 1
Calculate the mean carbon dioxide concentration in area B.
Answer
To calculate the mean carbon dioxide concentration for area B, we need to average the three measurements provided:
-
First, add the concentrations:
- 0.036 + 0.031 + 0.032 = 0.099
-
Next, divide the total by the number of measurements (which is 3):
- Mean = ( \frac{0.099}{3} )
- Mean = 0.033
Thus, the mean carbon dioxide concentration in area B is 0.033%.
