Explanation

If x centimeters is at the 73rd percentile, then approximately 73% of the measurements in the distribution are less than or equal to x centimeters. The 68 measurements that are greater than y centimeters but less than x centimeters are \frac{68}{850}*100%, or 8%, of the distribution. Thus 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.

There are 68 measurements between x and y. Now if x is at 73% what is % corresponding to y.

Since \frac{68}{850} \times 100 = 8% so % corresponding to y is 73% - 8% = 65%

Hence option E or 65% is correct.
