Question

mean of 6 observation is 17 of five observations are 14,9,23,25 and find the sixth observation​

Answer 1

Step-by-step explanation:

mean =sum of observations / no. of observations

17.5 = 14+9+23+25+10+x /6     

17.5 = 81+x /6

81+x =17.5 x 6

x = 105-81 =24

sixth observation is  24

hope it helps u !!

Answer 2

The mean of 6 observations is 17

so their sum is 17×6=106.

But the sum of 5 of them is 14+9+23+25+10=81.

So the 6th number is 102-81=21.
