The difference between Y and Y for a particular sample point (observation) is called a residual. Calculate the predicted Y (Y) for each of the dolphins, and then calculate the residuals. Dolphin Number of Treats Number of Attempts Predicted Y (Y) Residual Diana Frederick Fatima Marlin Use the regression line to estimate the number of trials it would take to learn these tricks if a dolphin received five treats per trick. Y for X - 5 would be The head dolphin trainer is pressuring you to teach the dolphins many new tricks quickly. She has asked you to use the least-squares regression line to predict how fast the dolphins can learn tricks if you were to give them 8 treats. Which of the following is the most appropriate response? The regression line predicts that the dolphins will need 1.5 attempts to learn a trick if they are given 8 treats. The regression line was estimated using 1 to 4 treats and should not be used to predict what would happen if the dolphins were given 8 treats. The regression line predicts that the dolphins will need 5.5 attempts to learn a trick if they are given 8 treats. Since the regression line predicts that the dolphins will need a negative number of attempts, you can assume the dolphins need 0 attempts if given 8 treats. To calculate the slope, first calculate SP and SS,: SP =, and ss. -The (Hint: For SP use the computational formula and for SS, use the definitional formula.) 2 . 4 The slope of the regression line is and the Y intercept of the regression line is
