Suppose an unbiased estimator
of a parameter e possesses a mound shaped distribution with E()=
= -12 and E( A
2) = 169.
Therefore, we can say that approximately 95% of the time
satisfies which of the following?
-10 < 0 – 0 < 10
-26 < Ö – 0 < 26
–15 < Ô – 0 < 15
-5 < ô – 0 < 5
- 22 < Ô – 0 < -2
- 38 <0 – 0 < 14
