Question

the mean of 10 observation 15.3if two observation 6 and​

Answer 1

Step-by-step explanation:

The mean of 10 observations = 15.3 Then sum of the 10 observations = 10 x 15.3 =153

If observation 6 and 9 are replaced by 8 and 14 respectively,

then the new sum of 10 observations = 153-(6+9) +8+14

=153-15+ 22=175-15

=160

So, the new mean of the 10 observations 160/10
