Directions: Find the best regression equation to fit the following tables of data. To find the best regression equation: 1) Enter the data into the calculator. 2) Find and state the regression equation and r for linreg, quadreg, expreg and lnreg. 3) Your answer will be the equation with the r closest to 1 or -1. Write your final answer. MODEL ...

a) Find the least squares regression line. State the equation below and interpret the slope and y-intercept. b) Find and interpret the value of r2. c) Create a residual plot on your calculator. What does this plot tell you about a linear model for this data? How do you know? d) Find and interpret the residual for 93°.
