Technicians measure heat flux as part of a solar thermal energy test. An energy engineer wants to determine how heat flux is predicted by the position of the east, south, and north focal points.
The engineer fits the regression model and uses it to calculate a range of likely values for future observations at specified settings.
Minitab uses the stored model to calculate that the predicted strength is 258.242. The prediction interval indicates that the technicians can be 95% confident that a single future value will fall within the range of 239.882 to 276.601.
