To find the percentile of a number, we simply use the formula:
[tex]Percentile= \frac{valuesbelow+0.5}{total observations} *100[/tex]
It has been given in the problem statement that there are 207 values below 88.6 and the total number of observations is 300. We simply just divide these and multiply the quotient by 100.
[tex]Percentile_{88.6}= \frac{207.5}{300}*100=69.17 [/tex]
ANSWER: 88.6 is in the 69th percentile.
