y = 1058x – 1174 Step 3: Check Correlation Looking at the data, most points are close to the line, but there are outliers (e.g., iPhone 15 Pro Max has a smaller battery than expected for its size). This suggests a moderate to strong positive correlation (estimated correlation coefficient r ≈ 0.85). 6. Conclusion (Answering the Question) Does a linear relationship exist? Yes. Our data supports the hypothesis that screen size and battery capacity have a positive linear relationship.
