If the data values were different (but still 7 values in the first column and 8 values in the
second column), what is the smallest U, could possibly be, and what is the largest Us
could possibly be?
Suppose that the value of 16 in the second column were instead 21. Would the resulting
U, and P values be larger or smaller? (Just circle Larger or Smaller for each.)
