There are 10 scores. The 90th percentile is the score with 9 below it.
Similarly, the 30th percentile is the score with 3 below it.
Did you check the related questions below?
Since the 3rd score is 105 and the 4th score is 113, I guess any score x where
105 <= x < 113
would work as the 30th %ile.
Not sure how the percentiles are demarcated in such discrete distributions. Maybe your text discusses the topic...
Find the values of the 30th and 90th percentiles of the data. Please show your work.
129, 113, 200, 100, 105, 132, 100, 176, 146, 152
