Hints to help answer this question
Use Microsoft Excel to graph the data in Table 1 using two scatterplots. Display 'Daily
Smokers' and 'Never Smoked' on separate graphs. Ensure you include the trend line,
equation and coefficient of determination (R2) on each of the graphs (Hint: go back and
revise Module 5).
Now verify the excel produced linear equation by using the manual methods for finding
the equation for a straight line. For this, select and use either the 'Daily Smokers' OR
'Never Smoked' data.
Use the Excel generated equations to manually (e.g. write all steps of the calculations)
predict what the 'Daily Smokers' and 'Never Smoked' data will be in 2023.
