Answer:
the 50th percentile = 66
The 25th percentile = 35
The 75th percentile = 85
Step-by-step explanation:
We have 11 numbers ,so we are dealing with an odd set of values.
Also ,we notice that the numbers are already in order.
then
the 50th percentile of the set 27, 34, 35, 48, 48, 66, 75, 85, 85, 96, 99
is the 6 number in the list [ 6 = (11+1)/2 ]
Which is 66.
The 25th percentile (the median) of the set 27, 34, 35, 48, 48
is the 3rd number [ 3 = (5+1/)2 ]
Which is 35.
The 75th percentile (the median) of the set 75, 85, 85, 96, 99
is the 3rd number [ 3 = (5+1/)2 ]
Which is 85.
