• kevin's percentile is 65
,• we will use the formula :
percentie of score x = [(number of data value less than x) /(Total number of data value )* 100]
65 = (number of data value less than x) /9740)* 100
Therefore : (number of data value less than x) =( 65 * 9740/100)
= 6331
• This means that number of student who scored less than 65 / less than Kevins 65 % = 6331,
