Answer:
see explanation
Step-by-step explanation:
Given
(5y + 6)² = 24 ( take the square root of both sides )
5y + 6 = ±
= ± 2
( subtract 6 from both sides )
5y = - 6 ± 2
( divide both sides by 5 )
y =
and y = 
Answer:
σˆ =

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

Let the derivative with respect to θ be zero:
l
0
(σ) = Xn
i=1 "

= 0
and this gives us the MLE for σ as
σˆ =

n
Again this is different from the method of moment estimation which is
σˆ =
sPn
i=1 X2
