In a conjoint study for evaluating preferences for a potential new high-speed commuter rail service between downtown Pittsburgh and Pittsburgh International Airport, the attributes and unscaled part-worths for the different levels are as follows:

(A) What is the relative importance weight of each attribute (so that they add up to 100%)? (6 points)

(B) Rescale the part-worths so that there are no negative part-worths and the rescaled part-worth of the least preferred level for each attribute is 0. Also, the highest part-worth of the most important attribute is 1.0 . (All other part-worths will then be between 0 and 1. (6 points)

Note that you do not need to solve one part before you can solve the other part. They can be solved independently
