The answer to the question is n+1
Answer:
σˆ =
sPn
i=1 X2
i
2n
Step-by-step explanation:
To obtain, the maximum likelihood ratio, we use the following method.
l(σ) = Xn
i=1 "
− log 2 − log σ −
|Xi
|
σ
#
Let the derivative with respect to θ be zero:
l
0
(σ) = Xn
i=1 "
−
1
σ
+
|Xi

σ

n
σ
+
Pn
i=1 |Xi
|
σ

= 0
and this gives us the MLE for σ as
σˆ =
Pn
i=1 |Xi
|
n
Again this is different from the method of moment estimation which is
σˆ =
sPn
i=1 X2
i
2n
As our answer
Nope
1/25 = 4%
25 is just 25
Answer:
50
Step-by-step explanation:
9. There are 4 odd numbers and 4 even numbers
P(odd number) = odd numbers/ total
= 4/ (4+4)
=4/8
= 1/2
If we spin 100 times, we multiply the number of times we spin * the probability
100 * 1/2 = 50
