Question

Question;ECO 500: Excel Assignment One;Below are data for U.S. DPI and PCE on two major components of;consumer spending, motor vehicles and parts and housing and utilities. One is;a durable good and the other is comprised of housing and other services and;non-durables, such as natural gas purchases. Using scatter diagrams and;trendlines, generate graphs showing the relationship of each of the;consumption categories to DPI and find the equation of the graph and the R;squared. Use your results to answer the questions to the right.;Questions;a);Plot the data using a;scatterplot.;b);Find the equation that;shows the relationship between motor vehicles and parts expenditure (PCE) and;DPI (insert a linear trendline and show the equation on the scatterplot).;c);Find the equation that;shows the relationship between housing and utilities expenditures (PCE) and;DPI (insert a linear trendline and show the equation on the scatterplot).;d);What are the R squares;for the equations? Which one is better? Can you provide an economic rationale;to explain the difference?;e);Use the equations to calculate;estimated values for both types of expenditures for 2011 and 2012. How well;did the equations predict values for 2011 and 2012?;Data;f);If DPI increases at a rate of 2.2%;in 2013 and then at a rate of 2.6% in 2014, what are the predicted values for;consumer spending on motor vehicles and parts?
