For this exercise refer to the following table, which gives the atmospheric concentrations of carbon dioxide (CO2) for selected years over the latter half of the 20th century. Year 1960 1985 1990 1995 1999 Atmospheric concentration of carbon dioxide (ppm) 316.75 345.73 354.04 360.91 368.37 Source: C. D. Keeling and T. P. Whorf, Scripps Institution of Oceanography (a) Let t 0 correspond to 1960, and assume an exponential growth model N 316.75ekt. Use the information for 1999 in the table to find the growth constant k. (b) Use the growth law determined in part (a) to make a projection for the CO2 concentration in 1985. Then, referring to the table, say whether the exponential model predicts too high or low a figure, and compute the percentage error. (c) Follow part (b) for the year 1990 and 1995. (d) Why do you think that the year 1999 was not included in part (c)? 1
