Question
# Educational Analysis: High-Fiber Breakfast Cereals ## Caloric and Sugar Content Data This lesson explores the relationship between the caloric content and sugar content in grams of 11 high-fiber breakfast cereals. You are tasked with finding the equation of the regression line based on the given data and constructing a scatter plot. The task also includes using the regression equation to predict the value of \( y \) for each given \( x \)-value, if meaningful. Consider explaining why it might not be meaningful when applicable. ### Data Overview - **Caloric Content (x):** - 150, 200, 160, 160, 170, 170, 190, 120, 200, 90, 160 - **Sugar Content (y):** - 6, 10, 6, 9, 11, 14, 16, 14, 20, 9, 11 ### Objectives 1. **Equation of the Regression Line:** - The regression equation is represented as \( \hat{y} = \text{Slope} \cdot x + \text{Intercept} \). - You are to calculate the slope and intercept, rounding to two decimal places as needed. 2. **Scatter Plot:** - Plot the data points using calories (x) as the independent variable and sugar content (y) as the dependent variable. - Draw the regression line on this plot. 3. **Prediction:** - Use the regression line equation to predict sugar content for the following caloric values: - (a) \( x = 160 \, \text{cal} \) - (b) \( x = 90 \, \text{cal} \) - (c) \( x = 175 \, \text{cal} \) - (d) \( x = 198 \, \text{cal} \) - Analyze whether each \( x \)-value is meaningful for prediction within the context of the data. By following these steps, you will gain insights into linear regression analysis and how to interpret statistical data effectively.
