Find the equation of the regression line for the given data. Round values to the nearest thousandth.
Madhur L.
Find the linear regression line for the following table of values. You will need to use a calculator, spreadsheet, or statistical software. Using the regression with values rounded to the nearest hundredth, find the value of y at x = 9. Round your answer to the nearest hundredth if necessary.
In $9-13 :$ a. Create a scatter plot for the data. b. Determine which regression model is the most appropriate for the data. Justify your answer. c. Find the regression equation. Round the coefficient of the regression equation to three decimal places. $$ \begin{array}{|c|c|c|c|c|c|c|c|c|}\hline x & {-2.3} & {1.8} & {-1.0} & {4.6} & {1.4} & {3.7} & {5.3} & {1.9} & {0.7} & {4.2} \\ \hline y & {2.2} & {18.3} & {83.7} & {15.3} & {43.0} & {89.5} & {22.7} & {12.1} & {54.7} \\ \hline\end{array} $$
