Extracted text: The plot below is a residual plot (residuals versus x) of residuals remaining after fitting a linear model to a set of data. Describe important features and determine if a linear model would be appropriate for this data set. Choose all answers that apply. A linear model would NOT be appropriate A linear model would be appropriate There is higher variability with smaller x There is higher variability with larger x
