2. Question 2: Suppose that you estimate a model of the aggregate annual retail sales of new cars that specifies that sales of new cars are a function of real disposable income, the average retail price of a car adjusted by the consumer price index, and the number of sports utility vehicles sold (you decide to add this independent variable to take account of the fact that some potential new car buyers purchase sports utility vehicles instead). You use the data (annual from 2000 to 2014) and obtain the following estimated regression equation: CARS, = 1.32+ 4.91Y D; + 0.0012 PRICE, - 7.14 SUV, (0.00045) | (2.39) (71.40) 1 where CARS, = new car sales (in hundreds of thousands of units) in year t, YD = real disposable income (in hundreds of billions of dollars), PRICE = the average real price of a new car in year t (in dollars), SUV; = the number of sports utility vehicles sold in year t (in millions). You expect the variable YD to have a positive coefficient and the variables PRICE and SUV to have negative coefficients. Create and test the appropriate hypotheses to evaluate these expectations at the 5% level.

1. Suppose that we are interested in measuring the relationship between hourly wage and output productivity in the U.S economy. Variables hrwage(t) and outphr(t) denote the average hourly wage and output productivity in the U.S economy for year t. We start by estimating the model specification shown in equation (1) below: log(hrwage) = Bo + B₁ log(outphre) + ut. where log(.) denotes the natural logarithm and ut is the error term. (a) Provide a brief interpretation of parameters 0 and 1 in (1).
2. Suppose you run a regression with quantity as your dependent variable and advertising as one of your independent variables. The p-value on advertising is .08. The marketing team is arguing that their advertising efforts are impacting sales, but the finance/economics department is arguing that there isn’t evidence that the advertising is impacting sales. What side would you take and why? Note that this question squarely hits the idea that stats is part science/part art...
Not a previously graded question. Please fill in both blanks below statement and answer bottom questions with either Included or Excluded. 1 . Activities included (and not included) in the calculation ofGDP The gross domestic product (GDP) of the United States is defined as the all in a given period of time. Based on this definition, indicate which of the following transactions will be included in (that is, directly increase) the GDP of the United States in 2021. Bottom choices are: Included or Excluded
Gross Domestic Product The following table givesthe gross domestic product (the value of all goodsand services, in billions of dollars) of the UnitedStates for selected years from 2000 to 2018.a. Create a scatter plot of the data, with y representing the GDP in billions of dollars and x representing the number of years after 2000.b. Find the linear function that best fits the data, withx equal to the number of years after 2000. Reportthe model with three significant digits.c. Graph the model with the scatter plot to see if theline is an excellent fit for the data.

Suppose the relationship between the government's tax revenue (T) and national income (Y) is represented by the equation T = 30 +0.5Y. Plot this relationship on a scale diagram, with Y on the horizontal axis and T on the vertical axis. Interpret the equation. Use the line drawing tool to draw the equation. Make sure to plot the vertical axis as one endpoint of the line. Properly label this line. Carefully follow the instructions above, and only draw the required objects.
The number of pending corporate fraud cases in federal court stood at 545 at the beginning of 2008 (t = 0). The number of cases had grown to 726 at the beginning of 2012. Assume the growth has been approximately linear. Develop the equation of the line that describes this linear growth. Then use that linear equation to estimate the number of cases pending at the beginning of 2014, assuming that the linear growth continues at the same rate.

Consider data on every game played by the Brooklyn Nets in 2014 (82 games) that includes the variables ● marginį - the Net's margin of victory (number of points the Nets scored minus the number of points their opponent scored) for game i, and home; - a dummy variable equal to 1 when the Nets are the home team (game i was played in their home arena) and equal to O when they are the away team (game i was played in the opponent's arena).
