Question:

Using the model of Example 4, estimate the concentration of carbon dioxide in the atmosphere in the year 1990.

Data from Example 4

Table 3 contains information about the concentration of carbon dioxide (CO₂) in the atmosphere. The linear regression model for the data is C = 360 + 2.04t where C is the concentration (in parts per million) of carbon dioxide and t is the time in years with t = 0 corresponding to the year 1995.

Interpret the slope of the regression line as a rate of change.

Use the regression model to predict the concentration of CO₂ in the atmosphere in 2025.
