Question

Angela took a general aptitude test and scored in the 83rd percentile for aptitude in accounting.

Answer 1

Answer:

(a) 83% of the scores were at or below her score.

(b) 17% was above her score.

Step-by-step explanation:

Given that:

Percentile score of Angela in the general aptitude test = 83rd percentile

To find:

a) Percentage of scores which were at or below her score?

b) Percentage of score which were above her score?

Solution:

First of all, let us learn about the term "Percentile"

Percentile is the value below which the certain percent of people/marks fall.

Therefore, when we say percentile of someone's score is $x$, then there are $x\%$ of scores are at the same level or below.

And $(100-x)\%$ of the scores are above this level.

Therefore, we can say that:

83% of the scores were at the same level or below the score of Angela.

And $(100-83)\% = 17\%$ of the scores were above the score of Angela.
