Answer 1

An element or an item that is in 60% of the number of element in that array (sorted).

Median is the 50th percentile.

For example if you have 100 elements in a sorted array, then the 60 percentile is your 60th element of array.

The index or position would be the 60% of the number of items.

Answer 2

In addition to Eve's good answer if the result of:

no.of.elements*60/100

is not a whole number you must round up the result.

In short (I'll use python syntax):
60th_percentile = math.ceil(len(array)*60/100)

eg. array with 101 elements:
60th_percentile = 61
i.e. the element at the 61-st index of the array.

Answer 3

complet the code for caculating and printing the 60th percentile of the data array. import numpy as np print(np.(data.60))
