Assume that variables xx and yy have a significant correlation, and that the line of best fit has been calculated as ˆy=1.4x+3.6y^=1.4x+3.6. One observation is (9,16.3)(9,16.3). What is the predicted value of yy for the value x=9x=9? What is the residual for the value x=9x=9? What is the best interpretation for the residual? The value 16.316.3 is below the average value for yy when x=9x=9 The value 99 is above the average value for yy when y=16.3y=16.3 The value 16.316.3 is above the average value for yy when x=9x=9. The value 16.316.3 is below the average value for xx when y=16.3

Assume that variables xx and yy have a significant correlation, and that the line of best fit has been calculated as ˆy=1.4x+3.6y^=1.4x+3.6. One observation is (9,16.3)(9,16.3).

What is the predicted value of yy for the value x=9x=9? 

What is the residual for the value x=9x=9? 

What is the best interpretation for the residual?

  • The value 16.316.3 is below the average value for yy when x=9x=9
  • The value 99 is above the average value for yy when y=16.3y=16.3
  • The value 16.316.3 is above the average value for yy when x=9x=9.
  • The value 16.316.3 is below the average value for xx when y=16.3
