(10 points) Please conduct regression analysis to study what factors influence theTotal Volume of Bookings. BasicallyTotal Volume of Bookingsis your dependent variable (Y) and your task is to determine what the important independent (explanatory) variables are. You should try different set of independent variables in the data set to see which one(s) has significant results (you may need to create dummy variables for some of the non-numerical variables). Please report 1) the final set of independent variables you have chosen andwhyyou have chosen them; and 2) the estimated regression equation with simple explanations foreach estimated coefficient (). (Hint:you may start with doing pair-wise correlations between Y and other variables to see what variables are significantly correlated with Y.)
