Given a set {x, y, z}, if the first term in the data set above is 3, what is the third term?

(1) the range of this data set is 0

(2) the standard deviation of this data set is 0

Doesn't matter 1st, 2nd or nth term is 3.

If one of the elements is "3" and the range of the set is 0; then all elements must be 3 irrespective of the order you write those elements.

Range 0- All elements identical.

Std Dev 0- All elements identical.

Ans: "D"
