Answers
Step-by-step explanation:
Given :-
The mean of the observations 6, 7, 9, 11, X, 12, 13, 14 is 10
To find:-
Find the value of x?
Solution:-
Given observations are :
6, 7, 9, 11, X, 12, 13, 14.
Sum of all observations =
=6+7+9+11+X+12+13+14
=72+X
Sum of all observations = 72+X
Number of all observations = 8
Mean = Sum of all observations/ Number of all observations
=>(72+X)/8
According to the given problem
Mean = 10
=>(72+X)/8 = 10
=>72+X = 10×8
=>72+X = 80
= >X = 80-72
=>X = 8
Answer:-
The value of X for the given problem is 8
Option D
Used formulae:-
- Mean = Sum of all observations/ Number of all observations
