Answer 2

Answer :-

Value of p = 13.

Explanation :-

Here, we are provided with mean of an observation.

• Observation = 4, 6, 7, p, 10.

• Mean of Numbers = 8.

We know that,

Mean = Sum of Numbers/Total Numbers.

Put the values.

⇒ 8 = (4 + 6 + 7 + p + 10)/5.

⇒ 4 + 6 + 7 + p + 10 = 8 × 5.

⇒ 17 + p + 10 = 40.

⇒ 27 + p = 40.

⇒ p = 40 - 27.

⇒ p = 13.

Therefore, Value of p = 13.
