**Exploring Regression and Scatterplots****Objective:**Use the given data to determine the equation of the regression line. Examine the scatterplot and identify a characteristic of the data that is ignored by the regression line.**Data Table:**| x | 10 | 9 | 11 | 10 | 14 | 5 | 4 | 12 | 6 | 6 ||----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|| y | 7.27| 6.8 | 13.16| 7.36| 7.69| 8.7 | 5.97| 5.42| 7.92| 6.36| 5.98 |**Instructions:**Create a scatterplot of the data. Choose the correct graph below.**Scatterplot Options:**- **A. (Incorrect)** - The points do not align with the given data. - **B. (Correct)** - The graph accurately represents the data points and shows a possible linear relationship.- **C. (Incorrect)** - The distribution of points does not reflect the given data.- **D. (Incorrect)** - The arrangement of points is not representative of the given dataset.**Task:**Find the equation of the regression line in the form \( \hat{y} = b + mx \).- **Round the constant to two decimal places as needed.**- **Round the coefficient to three decimal places as needed.**This exercise aims to improve understanding of data analysis, interpretation of scatterplots, and linear regression.
