Q:
# The residual plot for a data set is shown.Based on the residual plot, which statement best explains whether the regression line is a good model for the data set and why?The regression line is a good model because some residuals are 0.The regression line is not a good model because the points in the residual plot are far from the x-axis.The regression line is a good model because the residuals approach 0 as x increases.The regression line is not a good model because there is a pattern in the residual plot.

Accepted Solution

A:

Answer:The regression line is not a good model because there is a pattern in the residual plot.Step-by-step explanation:Given is a residual plot for a data set The residual plot shows scatter plot of x and y The plotting of points show that there is not likely to be a linear trend of relation between the two variables. It is more likely to be parabolic or exponential.Hence the regression line cannot be a good model as they do not approach 0.Also there is not a pattern of linear trend.D) The regression line is not a good model because there is a pattern in the residual plot.
