How do you interpret the price indices in Exhibit 3? How do economists construct them? Use Excel regression to analyze the relationship between the adjusted price index (dependent variable and year (independent variable). Interpret your regression findings by discussing the coefficient of determination (R- squared), the regression coefficient, the regression equation, and the p-value. Can you use the regression equation to predict the price indices? Take into account statistical, macroeconomic, and other considerations
