Sandor is trying to identify a linear relationship linking the amount of heat (x) applied in the final hardening stage to the heavy duty steel bolts that his company produces for bridge construction and the strength of those bolts (y). Below is a table showing data for a sample of five of the bolts.   Temperature vs. Strength Index Heat (oF) Strength index 2400 820 1800 600 2000 840 1200 620 2600 920 The slope for the least squares line is .22. The intercept is 320. Compute the "unexplained variation" (SSE).
