In deciding on where to locate their next grocery store, Publix narrowed it down to 3 locations (St. Augustine, the Airport area, or the Westside). They are using 2 criteria to make their decisions ? costs (with a weight of 70%) and customer base (with a weight of 30%). Each item was scored on a 10-point scale with 10 being the highest. St. Augustine rated a score of 4 for cost and 10 for customer base; the Airport area rated a score of 6 for cost and 5 for customer base; and the Westside rated a score of 8 for cost and 2 for customer base. Compute the mean score for each of the 3 locations.
