Question
Let x be the age of a licensed driver in years. Let y be the percentage of all fatal accidents (for a given age) due to failure to yield the right of way. For example, the first data pair states that 5% of all fatal accidents of 37-year-olds are due to failure to yield the right of way. x 37 47 57 67 77 87 10 17 28 44 Complete parts (a) through (e), given Ex = 372, Ey = 112, Ex = 24814, Ey = 3198, Exy = 8254, and r- 0.941. (a) Draw a scatter diagram displaying the data. Graph Layers After you add an object to the graph you use Graph Layers to view and edit its properties. No Solusion WebAssign. Graphing Tool (b) Verify the given sums Ex, Ey, Ex, Ey, Exy, and the value of the sample correlation coefficient r. (Round your value for r to three decimal places.) Ex = Ey = Ex? - Ey? - Exy = (c) Find x, and y. Then find the equation of the least-squares line ŷ = a + bx. (Round your answers for x and y to two decimal places.
