What is the 60 and 40th percentile?

Question

1 1 1 1 1 1 2 3 5 8 13 21 34 55 89 89 89 89 89 89

Answer 1

20 numbers, 6 ones, 6 89's. 8 numbers from 2 to 55

40th percentile divides bottom 40% from top 60%

40% of 20 = .4(20) = 8, find 8th from bottom = 3

60% of 20 = .6(20) = 12. find 12th from bottom = 21
