Sample Regression line provides estimate of population regression line. If the line is represented by Y= a + bx then to determine the equation of the regression line for a sample of data, the researcher must determine the values for 'a' and 'b'. Refer to the below data for X and Y variables. Can we use linear regression? Support your answer with a proper mathematical explanation. If yes, then determine the least squares regression line for this data. Also access the model fit. No. of Repair SI.
