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.

The table shows the yield (in bushels per acre) and the total production (in millions of bushels) for corn in a country for selected years since 1950. Let x represent years since 1900. Find a logarithmic regression model (y = a + b In x) for the yield. Estimate the yield in 2029. The regression model is y=+()Inx. (Round to one decimal place as needed.) ~ Year 1950 1960 1970 1980 1990 2000 2010 X Yield 50 60 70 80 90 100 110 41 54 85 96 110 146 158

Mark Gershon, owner of a musical instrument distributorship, thinks that demand for guitars may be related to the number of television appearances by the popular group Maroon 5 during the previous month. Gershon has collected the data shown in the following table: Maroon 5 TV Appearances Demand for Guitars This exercise contains only part a. a) Graph these data using the point drawing tool.

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.

A zero slope shows: positive relationship between two variables no relationship between two variables does not show anything negative relationship between two variables

Please show how to do b) and c). Quantity beef consumed is the dependent variable. Each of the others are the independent variables
