1) A teacher was trying to determine how a student's homework grade affected their test grade. She used the table below to record her findings: a) Use your calculator to construct the scatter plot. Sketeh the scatter plot on the graph above. b) Find the linear regression model. Round all values to the nearest Inendredih. Then find your correlation coefficient and round to the nearest thousandth. c) Sketch the residual plot for the linear regression model on the graph to the nght. d) Find the exponential regression model. Round all values to the nearest hundredth. Then find your correlation coefficient pnd round to the nearest thousandith. e) Sketch the residual plot for the exponential regression model on the graph to the right. f) Which is the best model for this data? Explain your choice making reference to the correlation coefficient and the residual plot. .
