How do I solve this? Below are 36 sorted ages of an acting award winner. Find the percentile corresponding to age 63

OpenStudy (amistre64):

how many data points are there?

OpenStudy (theislander):

36

OpenStudy (amistre64):

and it looks like they are listed in order (sorted) for you already so thats a plus. a percentile is a division by 100, we divide it into 100 parts. what position does 63 occupy in the ordered format?

OpenStudy (theislander):

20

OpenStudy (amistre64):

im looking at the 36 arent i

OpenStudy (amistre64):

63 is the 20th number .. youre right

OpenStudy (amistre64):

so, 20 out of 36 = x out of 100 is our comparison

OpenStudy (amistre64):

\[\frac{20}{36}=\frac{x}{100}\] this should give us the percentile of the number 63 in the data set

OpenStudy (theislander):

x=55.6

OpenStudy (amistre64):

and we need to round sooo ...

OpenStudy (theislander):

56

OpenStudy (amistre64):

56 feels good to me .... not saying its right, but that would be my approach

OpenStudy (theislander):

alright I'll give it a go. Thank for the help!

OpenStudy (amistre64):

56% of the data is 63 or less

OpenStudy (amistre64):

good luck
