Find the 34th percentile, P34, from the following data

1100 1200 1400 1600 1700

2300 2400 2800 2900 3000

3200 3300 3400 3800 3900

4300 4400 5000 5300 5400

5600 5900 6000 6200 6500

6700 7200 7300 7600 7700

8100 8400 8500 8600 8800

8900

P34 = __________

I took P/100 x n

34/100*36 =11.22

I am not sure if I did this right and not quite understanding it if you could explain to me better on how to figure out the percentile besides 50%. I am thinking it may be 2800 + 2900 =5700/2 = 2850 but not sure. Please explain and help me.
