The original data set is in the picture and the question parts needs to be answered as well for the original data set. Read and answer carefully and correctly.   Compute the mean, median, and mode for the data. Show your complete work.    (b) Compute a 5% trimmed mean for the data, and compare it with the mean computed in part (a). Does the trimmed mean more accurately reflect the general level of the daily rental costs?   If 5 will be added to each cost of condominiums, what will be the mean, median and mode?   If each cost of condominium will be added by 10 and multiplied by 2, what will be the mean, median and mode?
