​

Answer 1

Step-by-step explanation:

Solution :

Given,

         2,3,3,5,7,9,11                  [∵ Arrange it in an order wise]

To find,

Percentile rank P of score 5

           Percentile rank  P  =  $\frac{(100 ( i-0.5))}{n}$            [∵ formula]

   Here , i denotes the position of score we need to find.

              n denotes the number of data given                        

                              =   $\frac{100(4-0.5))}{7}$

                              =   $\frac{100(3.5)}{7}$

                              =   $\frac{350}{7}$

                              =    $50$

ANSWER :

       The Percentile rank of score 5 in the given data : 50
