Extracted text: A simple linear regression model was fitted to two variables: Y, the response variable and X, the explanatory variable. A scatter plot of Y versus X as well as the residual plot after fitting the least squares regression line to the data are given below. 0.4 0.35 0.3 0.25 > 0.2 0.15 0.1 0.05 2 10 X 0.2 0.15 0.1 0.05 10 -0.05 -0.1 Residuals


Extracted text: Which ONE of the following concerns with the assumptions for simple linear regression is NOT indicated by the plots? A straight line does not appear to be a good fit for the data. The scatter about the trend increases as x increases. There are doubts about the Normality of the errors. The relationship between x and y appears curved. The amount of variability in the residuals appears to depend on x.
