![Problem 6: For the following dataset, compute the means \( \bar{x} \) and \( \bar{y} \). Compute the "predicted values" for the linear predictor \( 2(x - \bar{x}) + \bar{y} \). Compute the deviations of \( y \) from the predicted values (i.e., the errors) and then compute the sum of squared error (SSE or SSD).
Dataset Table:
\[
\begin{array}{|c|c|}
\hline
x & y \\
\hline
3 & 2 \\
3 & 2 \\
2 & 3 \\
\hline
6 & 11 \\
\hline
\end{array}
\]
Now express the sum of squared error for the linear predictor \( m(x - \bar{x}) + \bar{y} \) as a quadratic polynomial in \( m \). Check that when you plug in \( m = 2 \) that you get your answer above.
Note: The table provided contains datasets for variables \( x \) and \( y \). The top three rows under \( x \) and \( y \) represent initial data points, while the bottom row seems to be an example of outlying data or for further comparison. The task involves calculating means and applying a linear predictor formula to find errors and SSE.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb20dd12d-5734-481d-b30d-eeb58ebe5d43%2F005df40c-0a4f-4fff-a9db-2bb0c0d2a960%2Flz59ns_processed.jpeg&w=3840&q=75)
