Could someone help me with this problem For the scores 3 5 8

Could someone help me with this problem!

For the scores 3, 5, 8, 10, 14, 17, 21, 25, calculate the 75th percentile using the following formula: R = P/100 x (N + 1) (Show work)

Here, there are 8 data points.

Thus, N = 8, then, as P = 75,

R = (75/100)*(8 + 1)

R = 6.75

rounding up,

R = 7

This means that we should get the 7th entry in this set, which is

75th percentile = 21 [ANSWER]
