Question

Jess has collected a set of data and calculated the range to be 18. She is then told to add the following numbers to the set: {23, 26, 44, 45} The new range of her data CANNOT BE A) 21 B) 23 C) 25 D) 27 57)

Answer 1

A) 21

Explanation:

21 is correct. Since the new numbers contain 45 and 23, the range of the new set must be 22 or larger, since 45 - 23 = 22.

Answer 2

The answer would be A. 21 Because the range between 23 and 45 would already be greater than 21.
