**Statistical Analysis: Linear Regression**This exercise involves finding the equation of a regression line using a set of data points.**Task Overview:**1. **Using the pairs of values for all 10 points:** - Find the equation of the regression line. 2. **After removing the point with coordinates (1, 2):** - Use the pairs of values for the remaining 9 points and find the equation of the regression line. 3. **Compare the results from parts (a) and (b):** - Evaluate how the removal of the point (1, 2) affects the regression line.**Step-by-Step Instructions:**a. **What is the equation of the regression line for all 10 points?** - Use the formula $\hat{y} = \text{[write the intercept]} + \text{[write the slope]}x$. Ensure to round the values to three decimal places as needed.**Note:** The problem prompts users to calculate the regression line equation interactively, so the specific numerical values for the intercept and slope are to be filled in based on calculation results. The image displays a coordinate grid with the x-axis ranging from 0 to 10 and the y-axis ranging from 0 to 10. There are several blue dots placed on this grid as follows:- A single dot located at the coordinates (1, 2).- A 3x3 square arrangement of dots, spanning from (3, 5) to (5, 7).These dots illustrate specific data points or positions on the grid, which could be used for various educational purposes such as teaching coordinate plotting or understanding geometric arrangements.

Answer a-c thank you
For the data in the table, find the regression equation and then use it to answer the questions below. Here, x gives a student's annual family income (in $1000's), and y is the student's SAT score. Round the slope and y-intercept to two decimals, then do not round your answer. Income SAT ($1000's) Score 62 940 66 950 75 960 77 980 78 990 79 1010 82 1020 86 1080 90 1090 100 1100 a. What is the predicted score for a student whose annual family income is $115,000? b. Is your answer to part (a) an extrapolation? O No: the value of x is within the range of the data, so the prediction is meaningful O Yes: the value of x is outside the range of data, so the prediction may not be meaningful
