Answer:
Pat's score therfore was the 20th percentiles
Step-by-step explanation:
When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.
In this problem, we have that:
34 scores lower than Pat's.
[tex]\frac{34}{170} = 0.20[/tex]
So Patrick's score was the 20th percentile.
