A double-mass curve is a graph of the cumulative catch at the rain gage of interest versus the cumulative catch of one or more gages in the regions that have been subjected to similar meteorological occurrences and are known to be consistent. The annual rainfalls of gage A,B, C and D are given in table below. Gage D was permanently relocated after a period of 3 years (at the end of 1988). Adjust the recorded values from 1986 through 1988 of gage D using double mass curve with the assumption that the other gages are consistent. Give your answers for the adjusted data in order (1986, 1987, 1988). Give your answers rounded off to the nearest hundredths. Submit your solution and the double - mass curve for both on the folder provided.
