What is a percentile?

A percentile is a score that relates one rating to the scores of the rest of the group. It represents the proportion of scores that a given score surpassed.

We have:

x = 0

y = 120 seconds

Percentile:

= x + (y - x)p

= 0 + (120 - 0)0.8

p = 80% = 0.8

Percentile = 96 seconds

Thus, the value of x is 96 seconds if the amount of time you have to wait at a particular shoplift is uniformly distributed between zero and two minutes.
