In the discussion of Nissan's Leaf, we looked at two hypothesis tests for the same 6 measurements of the range.

The second test gave Nissan the benefit of the doubt and found we would not reject their claim based on this data. The conclusions appear contradictory. This chart illustrates assuming the population mean is 74 or 77 miles.
