Measurements of the electrical resistivity of tungsten at specified temperatures are presented in the table below. The error in the determination of the temperature was negligible. The temperatures are stated as absolute temperatures in °K. The units of resistivity are u Ncm . Carry out a regression analysis for resistivity as a function of temperature.

When examining a plot of the residuals produced by the regression model, which of the following statements are true The residuals should be both positive and negative values. They should expand outward, producing a conical shape as your predicted y value increases in size. The residuals should show a clear positive relationship. Low values of your independent variable should produce negative residuals, while high values of your independent variable should produce positive residuals. The residuals should produce a clear u-shaped patter. All values should be positive. The residuals should appear to be random, with a horizontal band around the x- axis. They should be both positive and negative values.
