Civil Engineering: Soil Profiles Sand and clay studies were conducted at the West Side Field Station of the University of California. (Reference: Professor D. R. Nielsen, University of California, Davis.) Twelve consecutive depths, each about 15 cm deep, were studied and the following percentages of clay in the soil were recorded. 47.4 43.4 48.4 42.6 41.4 40.7 46.4 44.8 36.5 35.7 33.7 42.6 (i) Convert this sequence of numbers to a sequence of symbols A and B, where A indicates a value above the median and B a value below the median. (ii) Test the sequence for randomness about the median. Use a

EX: 1 2 3 4 5 6. The two middle terms are 3 and 4 so 3 + 4 = 7. Then 7/2 = 3.5 (finding...
