In a distribution of 850 different measurements, x centimeters is at the 73rd percentile. If there are 68 measurements in the distribution that are greater than y centimeters but less than x centimeters, then y is approximately at what percentile in the distribution?
A. 45th
B. 50th
C. 55th
D. 60th
E. 65th
OEIf x centimeters is at the 73rd percentile, then approximately 73% of the measurements in the distribution are less than or equal to x centimeters. Te 68 measurements that are greater than y centimeters but less than x centimeters are (68/850)(100%), or 8%, of the distribution. Tus approximately 73% - 8%, or 65%, of the measurements are less than or equal to y centimeters, that is, y is approximately at the 65th percentile in the distribution.
The correct answer is Choice E.
