Make a scatter plot of this data. Which point is an outlier?

 Enter as an ordered pair. For example (a,b) - with parenthesis.


Find the regression equation for the data set without the outlier.


   Enter as an equation of the form y=a+bxy=a+bx. Rounded to three decimal places. Do not include the hat in y-hat.


Find the regression equation for the data set with the outlier.


   Enter as an equation of the form y=a+bxy=a+bx. Rounded to three decimal places. Do not include the hat in y-hat.

Is this outlier an influential point?

  • Yes, the outlier appears to be an influential point.
  • No, the outlier does not appear to be an influential point.
