Five years ago, a company experienced some extremely unusual events, including a major strike and a widely publicized health concern about one of its products. Since the firm tended to hit bottom during the time, the year would be a good choice as a base period for an index reflecting production volume.
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.
Suppose output (Q) is related to labor (L) and capital (K) in the following nonlinear way: Q = aLbKc When taking log to this equation, it is transformed into a linear LnQ = lna + b ln(L) + c Ln (K) One hundred twenty-three observations are used to obtain the following regression results: Dependant Variable: Q R-square F-ratio p-value on F Observations: 123 0.7547 184.56 0.00001 Variable Parameter Estimate Standard error t-ratio p-value Intercept 5.5215 0.9750 5.66 0.0001 L 0.650 0.2950 2.20 0.0295 K 0.350 0.1450 2.41 0.0173 A.

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.
