A total of 100 maintenance costs, C, for ground-mounted transformers in high-density housing areas was collected by the City Electricity Authority. The costs are clustered into $200 cells with midpoints ranging from $600 to $2000. The number of times (frequency) each cell value was observed and its probability are shown. Find the expected value of the costs, E(C), for use in a presen worth (PW) analysis.
