Question

The mean of 5 observations is 4.8 and the
variance is 6.56. Ifthree of the five observations
are 1, 3 and 8, find the other two observations.​

Answer 1

Step-by-step explanation:

we take x for remaining 2 observations

4.8=1+3+8+x+x/5

4.8×5=12+2x

24-12=2x

12/2=x

6=x

other two observations are 6,6.
