Question

The mean of 8,11,6,14,x and 13 is 66.Find the value of the observation x.

Answer 1

(8+11+6+14+ x+ 13)/6=66

(52+x)=396

X=344

Answer 2

Step-by-step explanation:

MEAN = 66

• MEAN = SUM OF OBSERVATION / NUMBER OF OBSERVATION
• 66 = 8+11+6+14+13+x/6
• 66*6 = 8+11+6+14+13+x
• 396 = 52+x
• 396-52 = x
• 344 = x
• THEREFORE, THE VALUE OF THE x IN THE ABOVE OBSERVATION IS 344
