Unformatted text preview: In the topic of least squares regression, the idea is to fit a “ best-fit ” line such that the residual sum of squares is minimized. The residual sum of squares, RSS, is measured by ??? = ° ± 2 ± ² =1 , where n are the residuals. If there are 15 data points in a particular set of analyses, and the residuals are normally distributed with mean = 0 and variance = 16, find P(RSS > 400)....
