SimpleLinearRegression and Multiple Regression.
I'd like to ask whether you think multiple regression (the use of more IV's) is always better than simpleregression? Why or why not?
What problems may exist with multiple regression that are not an issue forsimplelinearregression?

Consider the following partial computer output from a simplelinearregression analysis from the data provided in the attached document.
What is the estimated y-intercept?
What is the estimated slope?
Write the equation of the regression line.
What is the predicted value of y when x = 1,000?
Calculate the correlation

One of the assertions is that changes in Federal Reserve policy can affect inflation. Using the data on the growth rate of M2 and inflation in your spreadsheet, run a regression of the rate of inflation on the rate of growth of the money supply. Do the data support a connection between the rate of increase in the money supply a
