Exercise 4.44 (page 124) gives data on annual average global temperatures for the last 22 in degrees Celsius. n GTEMPS years (a) Find the least-squares regression line for predicting average global temperature from year. Make a scat- terplot and draw your line on the plot. (b) Explain in words what the slope of the regression line tells us. (c) An environmentalist uses the line, based on the years, to predict average global temperatures in 2050. What is the prediction? How reliable do think your prediction is? 20 you 121)
