"A sample consisting of four pieces of luggage was selected from among those checked at an airline counter, yielding the following data on x = weight (in pounds). x1 = 33.3, x2 = 27.4, x3 = 36.9, x4 = 30.8
Suppose that one more piece is selected and denote its weight by x5.
Find all possible values of x5 such that x = sample median."
