14. Exercise 4 (page 278) gives data on CO2CO2 concentration (in parts per million) over time. A regression line for predicting CO2CO2 for a given year is

predictedCO2concentration=311.662+1.43866(yearselapsedsince1959)predictedCO2concentration=311.662+1.43866(yearselapsedsince1959)

Page 281

  1. What is the slope of this line? What does the slope say about how CO2CO2 is changing over time?
  2. What does the model predict the CO2CO2 concentration for 2006 to be? In fact, the observed value that year was 381.85. How accurate is your prediction?
