![### Regression Analysis and Scatter Plot Interpretation
**Objective:**
Find the equation of the regression line for the given data. Construct a scatter plot of the data and draw the regression line. Use the regression equation to predict values based on x-values.
**Data:**
The table below shows the caloric content and the sodium content (in milligrams) for 6 beef hot dogs:
- Calories (x): 160, 170, 130, 130, 90, 180
- Sodium (y): 430, 480, 350, 370, 270, 550
**Regression Equation:**
The equation of the regression line is given by:
\[
\hat{y} = 2.915x + (-9.578)
\]
Round to three decimal places as needed.
**Tasks:**
1. Use the regression equation to predict the value of \( y \) for each given \( x \)-value, if meaningful:
- (a) \( x = 180 \) calories
- (b) \( x = 100 \) calories
- (c) \( x = 150 \) calories
- (d) \( x = 50 \) calories
**Graph Selection:**
Choose the correct scatter plot with the drawn regression line from the options A, B, C, or D.
**Graph Details:**
- **Axes:** The horizontal axis represents Calories (x), while the vertical axis represents Sodium (mg) (y).
- **Scatter Points:** Each plot contains points representing the caloric and sodium content of the hot dogs.
- **Regression Line:** A line indicating the trend and relationship between the variables overlaid on the scatter plot.
**Support:**
- "Help me solve this" and "View an example" options provide additional guidance.
**Note:**
Selecting the correct graph involves comparing the plotted points and regression line with the data and the calculated regression equation.
