Explanation / Answer

(a) The top score is 77.

The ranks of 37 are 14 and 15

P = R * 100 / (n+1)

n = 32

=> P = 14 * 100 / 33 and P = 15 * 100 / 33

=> P = 42.42 and P = 45.45

Average percentile rank P = (42.42 + 45.45) / 2 = 43.935 = 44th percentile.

(Note: The definition of percentile varies. Some consider the average, others the highest or lowest value. In case 44 does not work, try entering 45, 42 or 43.)

The rank of 73 is 29.

P = 29 * 100 / 33

= 87.88

= 88th percentile.
