Find the values of the 30th and 90th percentiles of the data. 129, 113, 200, 100, 105, 132, 100, 176, 146, 152
A. 30th percentile = 105; 90th percentile = 200
B. 30th percentile = 113; 90th percentile = 200
C. 30th percentile = 105; 90th percentile = 176
D. 30th percentile = 113; 90th percentile = 176 **Weegy:** 90th percentile is simple another way of saying that 9% scored above and 90% scored below (the other 1% being the number 90). [ [
For example, if you take a type of standardized test in high school, if you do well, you are at the 90th percentile, meaning 90% of students scored lower than you and 9% scored better. You can not be in the 100% percentile, because you cannot score better than yourself.
