1. The problem asks for the regression equation of a quadratic model based on the given data points relating Instagram screen time and number of alcohol-impaired driving deaths. 2. The general form of a quadratic regression equation is: $$y = ax^2 + bx + c$$ where $y$ is the dependent variable (Instagram screen time), $x$ is the independent variable (number of alcohol-impaired driving deaths), and $a$, $b$, and $c$ are coefficients to be determined. 3. To find the coefficients $a$, $b$, and $c$, we use the method of least squares fitting on the data points. 4. Since the exact data points are not numerically provided here, the regression equation cannot be explicitly calculated without the data. 5. However, the quadratic regression equation will model the wavy pattern observed in the scatter plot, capturing the curvature in the relationship between screen time and deaths. 6. If you provide the numerical data points, I can compute the exact quadratic regression equation for you.
