2a. For the following data compute, a (intercept), b (slope) and write the Regression equation. Please show all computations, clearly mark the answer for the intercept, slope and the Regression Equation. (6 points) Note: 2 points for a (intercept), 3 points for b (slope) and 1 point for the regression equation.
