The graph in Exercise 64 shows the number of student y enrolled in public colleges for selected years x , where x is the number of years since 1990. The table gives a partial list of data from the graph. a. Use the data in the table to find the least-squares regression line. Round the slope to 2 decimal places and the y -intercept to 1 decimal place. b. Use a graphing utility to graph the regression line and the observed data. c. Assuming that the linear trend continues use the model from part (a) to predict the number of students enrolled in public colleges for the year 2020. d. By how much do the results of part (c) differ from the result of Exercise 64(d)?
