the following residual plot is obtained after a regression equation is determined for a set of data.
does the residual plot indicate that the regression equation is a good model or a bad model of the data? why or why not?
a)the residual plot suggests that the regression equation is a good model. the residual plot becomes thinner when viewed from left to right, which suggests that for different fixed values of x, the distributions of the corresponding y-values have different standard deviations.
b)the residual plot suggests that the regression equation is a bad model. the residual plot becomes thinner when viewed from left to right, which suggests that for different fixed values of x, the distributions of the corresponding y-values have similar standard deviations.
c)the residual plot suggests that the regression equation is a bad model. the residual plot becomes thinner when viewed from left to right, which suggests that for different fixed values of x, the distributions of the corresponding y-values have different standard deviations.
d)the residual plot suggests that the regression equation is a good model. the residual plot becomes thinner when viewed from left to right, which suggests that for different fixed values of x, the distributions of the corresponding y-values have similar standard deviations.
