Question
the values are in the 2nd picture under Example 2
Math 11 Elementary Statistics
Example 2:
0.00, 0.08, 0.13, 0.14, 0.16, 0.17, 0.20, 0.29, .056, 0.70, 0.79
L = .25(11) = 2.75 which rounds to 3, so the 3rd number is the 2
percentile
and its value is
L = .50(11) = 5.5 which rounds to 6, so the 6th number is the 50t
percentile, or the median
and its value is
L = .75(11) = 8.25 which rounds to 9, so the 9th number is the 75
percentile

Example 4: Use the same data, from example 2.
Find the percentile of 0.29
There are 7 values less than 0.29
The percentile = 100[(7 + 0.5)/11] = 68.18 or 68.2
%3D
So the result 0.29 corresponds to the 68th percentile.
