Table 1.12 gives the population of California for several years.

(a) Let x = 0 represent 1980, x = I represent 1981, and so forth. Find an exponential regression for the data, and superimpose its graph on a scatter plot of the data.
(b) Use the exponential regression equation to estimate the population of California in 2003. How close is the estimate to the actual population of 35,484,000 in 2003?
(c) Use the exponential regression equation to estimate the annual rate of growth of the population of California.
