Answer:
mean of 10,12,18,13,P and 17 is
(10+12+18+13+P+17)/6
=(70+P)/6
so,
70+P/6=15
=> 70+P=15×6
=> 70+P=90
=> P=90-70
=> P=20
value of P is 20

Step-by-step explanation:
Given:-
The mean of 10, 12, 18. 13, P and 17 is 15
To find:-
Find the value of P ?
Solution:-
Given observations are : 10, 12, 18, 13, P and 17
Sum of all observations
= 10+12+18+13+P+17
=70+P
Sum of all observations = 70+P
Number of all observations = 6
We know that
Mean = Sum of all observations/Number of all observations
=>Mean = (70+P)/6
According to the given problem
Mean of the above observations = 15
=>(70+P)/6 = 15
=> 70+P = 15×6
=> 70+P = 90
=> P = 90-70
=> P = 20
Therefore, P = 20
Answer:-
The value of P for the given problem is 20
Used formula:-
Mean = Sum of all observations/Number of all observations
