The image displays an exercise related to finding the equation of a regression line for a given dataset. The dataset provides the caloric content (in calories) and sodium content (in milligrams) for six beef hot dogs. Here is the transcription and explanation of the content: **Dataset:** - **Calories (x)**: 150, 170, 120, 120, 80, 190 - **Sodium (y)**: 410, 460, 350, 370, 260, 520 **Task:** - Find the equation of the regression line for this data. - Construct a scatter plot and draw the regression line. - Use the regression equation to predict the value of \( y \) for the given \( x \)-values, if meaningful. **Given \( x \)-values:** - \( x = 160 \) calories - \( x = 100 \) calories - \( x = 130 \) calories - \( x = 220 \) calories **Regression Equation:** - The equation format is \( \hat{y} = \text{(slope)} \times x + \text{(y-intercept)} \). - You need to round to three decimal places as needed. **Interactives:** - Options to “Help me solve this,” “View an example,” and “Get more help” are provided. - A "Check answer" button is available for students to submit their responses. This exercise teaches students how to apply statistical methods to analyze relationships between variables by constructing and utilizing regression lines.
