In your memo, discuss these various equations and state which of the equations you would recommend to be used and why. Provide a complete and detailed justification for your choice. Also, discuss the meaning of the regression coefficients of the equation that you choose and explain whether these coefficients are reliable by referring each to its t-value. Attach your Excel work for this section to your memo. In your regression equation, carry two decimal points for coefficient of X variables and none for the intercept. (Hint: Your selection should be based on highest R' and t-values or P-values.)
