Question

can you please do the graph part . i dont no where to out the regression line on the graph

5. Computing the regression line and making predictions Aa Aa Suppose you are a dolphin trainer at SeaWorld. You teach the dolphins by successful attempt at a new trick. The following table lists the dolphins, the number of treats per su each, and the average number of attempts necessary for each to learn to perform the tricks. rewarding them with fish treats after each ccess given to Number of Number of Dolphin Treats Attempts Diana Frederick Fatima Marlin You can use the preceding sample data to obtain the regression line, where ? is the predicted value of Y: bX + a One formula for the slope of the regression line is as follows SP To calculate the slope, first calculate SP and ss: SP5.00 and SSx-5.00 (Hint: For SP use the computational formula and for Ss use the definitional formula.) TTP& B&rticular sample point (observation) is called a residual.Calculate the predicted Y () for each of the dolphins, and then calculate the residuals Number of Number of Dolphin Treats Attempts Predicted Y (9) Residual Diana 7.5 0.5 -0.5 0.5 0.5 5.5 Fatima Marlin 6.5 On the following scatter plot of the blue sample points (clrdle symbol), use the orange points (square symbol) to plot the regression line. Make sure that the orange line spans the entire graph (from left to right). A line segment will automatically connect the points NUMBER OF ATTEMPTS 10 Regression Lin NUMBER OF TREATS 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. 9 for X-5 would be 4.5
