2-7 Linear Regression, Correlation, CausationDate_____ I can create and use a line of best fit both by hand (using two points) and using technology (linear or exponential). I can explain the meaning (using appropriate units) of the slope and y-intercept of a linear function in a real-world situation.

regression equations. In this packet you will be calculating different regression equations. (Each problem will tell you which regression equation to calculate) Your calculator will find the equation for you. After we find the equation to represent the points (data), we need to know how well the equation matches the data.

Your calculator can find the equation of the line of best fit through a process called linear regression. This is a statistical calculation, so the command is found in the STAT CALC menu 4:LinReg(ax+b). Note that the calculator uses a for the slope and b for the y-intercept. Hit ENTER to bring the command to the home screen and ENTER again to ...

Draw a best-fit line by hand or use the linear-regression feature of your calculator or Graphical Analysis and determine the slope. The slope can be used to determine the acceleration of the cart on an incline of any angle. On the graph, carry the fitted line out to sin(90() = 1 on the horizontal axis, and read the value of the acceleration.

The correct answer is (b). I is incorrect—the predicted weight of a person 61 inches tall is 104.6 pounds. II is a correct interpretation of the slope of the regression line (you could also say that "For each additional inch of Height, Weight is predicted to increase by 3.6 pounds). III is incorrect.
