(a) Construct a scatter plot for this data. (Either by hand or using Excel)

(b) Comment on the shape.

(c) Find a line of best fit.  If doing this by hand, you will need to find the line of best fit by eye and then find the equation.  If using excel, use a formula(s) to find the line of best fit.

(d) Using the equation, what was/is the atmospheric CO2 in 2005, 1920, 2020?  Comment on the accuracy of your answers.

(e) In your conclusion, comment on the accuracy of modelling this as a straight line given your graph.  Consider the accuracy to determine past and present values for CO2.
