Data Representation context: A sensor reported mean chlorophyll and uncertainty range for four samples. Data table: Sample A mean = 9 with range 8-10; Sample B mean = 12 with range 11-13; Sample C mean = 10 with range 9-11; Sample D mean = 14 with range 9-16. New information: A sample is confidently above the threshold only if its entire uncertainty range is above 10 units. Which sample is confidently above the threshold?
