A sample consisting of four pieces of luggage was selected from among the luggage checked at an airline counter, yielding the following data onx= weight

(in pounds).

x₁=33.6,x₂=27.2,x₃=36.1,x₄=30.7

Suppose that one more piece is selected and denote its weight byx₅.

Find all possible values ofx₅

such thatx= sample median.
