The independent variable is the number of pages (x) and the dependent variable is cost (y).The sample size is n = 11. Consider the below table. The general form of the linear model is y = b0 + b1x, where b0 is the y-intercept and b1 is the slope coefficient. The slope of the linear model is, Hence, the linear model is y = 23.25 + 0.10x. Substitute x = 569 in the linear model. That is, y = 23.25 + 0.10(569) = 80.15. Thus, the estimated cost when number of pages is 569 is $80.15.
