P25 measn 25% of the values ra eless than P25
It is given by kx(n+1)/100 th observation
= 25 x(36+1)/100= 9.25th observation
Now we can either select the 9th value or we can interpolate between 9th and 10th value to approximate the 9.25th vale - Refer your text to see which method is used in text
If 9th value is to be take, the P25 is 34
If 9.25th value is to be taken, P25 is 34 + (37-34)x0.25 = 34.75
