A library has been given 3 books. these books carry volume numbers X1, X2 and X3 where

X1<X2<X3. But it is not known how many volumes there are altogether in the set. Suppose there are n volumes, numbered 1,2,3,...n in the set, and the 3 volumes in the library are regarded as a random sample from this total of n. Two estimators of n are proposed:

Y=2(3X3-X1)

Z=2X2-1

Consider the case where n is 3. show that the value of Y must be 4 and that the value of Z must be 3.

2. Relevant equations

3. The attempt at a solution

I know i have to find X1 and X2 and X3 but i dont know how to start.

Thank you!!
