I´m struggling with this Manhattan question:
"Jane scored in the 68th percentile on a test, and John scored in the 32nd percentile.
A: The proportion of the class that received a score less than John’s score.
B: The proportion of the class that scored equal to or greater than Jane’s score."
The answer is supposed to be C, but suppose 101 people were graded, and all of them obtained a different score. If we order all scores in ascending order, John is in the position 33 and Jane is in the position 69. Thus, quantity A equals 32/101 and quantity B equals 33/101, which are not equal.
I guess I must be making a mistake, although I cannot see it yet. I would appreciate any help on this. Thanks!
