The x-axis (average weekly hours studying) ranges from 0.0 to 20.0 in increments of 5.0. The y-axis (residuals) rises from negative 0.3 to 0.4 in increments of 0.1. The plotted points form a roughly funnel shape around the x-axis, with many points on the left side (under 5.0 hours) extending both above and below the axis, then becoming much fewer and closer to the axis as average weekly hours increases to 15.0.

Based on the residual plot, do you think that this regression model is a good fit? Explain
