Suppose that you have generated 3 alternate multiple regression equations to explain the variations in a particular dependent variable. The regression output for each equation can be summarized as follows:                        Equation 1           Equation 2         Equation 3 No of Xs               4                              6                                9 R2                             0.76                        0.77                        0.79 Adjusted R2        0.75                        0.74                        0.73 Which one of these equations would you select as “best”?  Explain your choice

A building contains 1000 light bulbs. Each bulb lasts at most 5 months.  The company maintaining the building is trying to decide whether it is worthwhile to practice a group replacement policy where all bulbs are replaced every T months (T is yet to be determined).  Also bulbs are replaced as they burn out. Assume that it costs $0.05 to replace a bulb during a group replacement and $0.20 to replace each burned-out if it is replaced individually.  How would you use simulation to determine whether a group replacement policy is worthwhile?
