Answer 1

I don’t have the scatter plot or the list of points, so I can’t tell which ordered pair is the outlier. Could you either
- paste the data points, or
- upload/describe the scatter plot (coordinates or a clear image),

If you want to find the outlier yourself, here are two quick methods:

1) Visual method
- List the plotted (x,y) points.
- Look for any point that is far away from the overall pattern/trend of the other points (that is the outlier).

2) Numeric method (more objective)
- Fit a least-squares line to the points (or identify the expected trend).
- Compute residuals: residual = observed y − predicted y.
- Points with very large absolute residuals (common thresholds: |residual| > 2·SD(residuals) or studentized residual > 2 or >3) are outliers.

You started typing “5,” — if you mean the point has x = 5, tell me the y (for example “5,12”) or give me the whole list and I’ll identify the outlier(s) and show the calculations.
