Answer:

P = 25

Step-by-step explanation:

x                y               xy

3               6               18

5               8               40

7               15              105

9               P                9P

11              8                88

13             4                52

              ------           ------------

              41 + P           303 + 9P

∴ Mean = ∑xy/∑y

⇒ 8 = (303 + 9P)/(41 + P)

⇒ 8(41 + P) = 303 + 9P

⇒ 328 + 8P = 303 + 9P

⇒ 25 = P

Therefore, the value of P is 25.

Hope it helps!
