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.
