The following moisture-density data are results from laboratory compaction tests on a given soil using the same compactive effort:

(a) On a suitable graph or using a spreadsheet, plot the curve of dry unit weight versus water content and indicate the maximum dry unit weight and the optimum water content.

(b) What range of water contents would be acceptable if the specifications call for 98% relative compaction and water content should be dry of optimum? Show how you calculated the relative compaction and show on the plot the range of water contents.
