Thank you for the opportunity to help you with your question!

71 is in group number 27

The lower class limit of 27 is 26.5

The percentile of 26.5 = 26.5/32 *100 =82.81%

Rounding off brings the percentile to 83rd

Please let me know if you need any clarification. I'm always happy to answer your questions.
