Xis the number of days per week that100clients use a particular exercise facility.

n=100

Note the 0.80in the "cumulative relative frequency" column to find the 80th percentile.

The 80th percentile is somewhere between 3and 4.We don't have any X values between 3and 4, however. All X values are 4 from the 76thpercentile to the 87thpercentile.

As a result, the80thpercentile is 4.
