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 = 33.1, x2 = 27.2, x3 = 36.1, x4 = 30.4
Suppose that one more piece is selected and denote its weight by x5.
Find all possible values of x5 , such that
x = sample median.
