Answer 2

Given : Mean of the distribution is 21

To Find:  Value of the P

Solution:

x             d= x- Mean           f               df

12            -9                         8             -72

18            -3                         3              -9

20           - 1                        7                -7

25            4                         4              16        

p + 6         p - 15                  6            6p - 90

                                                       6p - 162

6p - 162 = 0

=> p = 27

Hence value of the p is 27
