Transcribed Image Text:The image features a scatter plot graph depicting the relationship between the "Average consumption of vegetable products in kg" (x-axis) and "Percent Obese" (y-axis). Each blue dot represents data points collected in a study.
**Graph Details:**
- **X-axis:** Ranges from 20 to 50 kg, representing the average consumption of vegetable products.
- **Y-axis:** Ranges from 0 to 50 percent, indicating the percentage of obesity.
- **Trend Line:** A dotted line sloped downwards, suggesting a negative correlation. The equation of the line is \( y = -0.8449x + 50.328 \).
**Key Information:**
- **Correlation Coefficient:** 0.5, indicating a moderate negative correlation between vegetable consumption and obesity rates. As vegetable consumption increases, obesity rates tend to decrease.
Expert Solution
Step 1
From the above graph and regression line
Linear Regression Equation for this data: y = -0.8449x + 50.328
So the Correlation Coefficient=r=-0.5
