1. A researcher is using data for a sample of 32 companies to investigate the relationship between annual spending Yi (measured in millions of dollars per year) and annual firm profits Xi
(measured in millions of dollars per year). Preliminary analysis of the sample data produces
the following sample information:
EY = 4,917
Xi = 11,856 EY? =4,022,814
x2 =25,796,522.5 EXY =9,785,312
A. Estimate a regression function Y = f(x) and Interpret the slope coefficient you estimate.

Uppose that the federal reserve purchases a bond for $100,000 from donald truck, who deposits the proceeds in the manufacturer’s national bank. what will be the impact of this purchase on the supply of money? the money supply will increase by $100,000. the money supply will increase by $80,000. the money supply will increase by $500,000. this action will have no effect on the money supply. if the reserve requirement ratio is 20 percent, what is the maximum amount of additional loans that the manufacturer’s bank will be able to extend as the result of truck’s deposit? the maximum additional loans is $100,000. the maximum additional loans is $80,000. the maximum additional loans is $20,000. the maximum additional loans is $500,000. given the 20 percent reserve requirement, what is the maximum increase in the quantity of checkable deposits that could result throughout the entire banking system because of the fed’s action? this action will have no effect on the money supply. the money supply will eventually increase by $80,000. the money supply will eventually increase by $500,000. the money supply will eventually increase by $100,000.
