Answer:

Kindly check explanation

Step-by-step explanation:

Given the data on the result of math exam in Ben's class

{35,42,56,68,69,72,72,77,78,78,82,85,87,88,90,93,94,96,96,99}

The 85th percentile score represents the score in which 85 percent of the students in Ben's class or below obtained in the test.

The 85th percentile score :

85%(n+ 1) term

n = number of observations = 20

0.85(20 + 1)th term

0.85(21) = 17.85 term

Take the average of the 17th and 18th terms

(94 + 96) / 2

= 190 / 2

= 95
