Answer: C
Explanation:
First, rearrange the data from least to greatest: 45, 47, 54, 59, 81, 90
- The range = greatest value(max) - smallest value(min).
- The current range = 90 - 45
Substitute in each of the answer choices, subtract the minimum value from the maximum value, and find one that result in 50.
- A. 90 - 44 = 46
- B. 130 - 45 = 85
- C. 90 - 40 = 50
- D. 90 - 6 = 84
