A) -10
B) -20
C) -5
D) 10
Correct Answer: B
Solution :
[b] \[\mu =20,{{\sigma }^{2}}=2\] and \[p\mu -q=\frac{20}{2}\Rightarrow 20p-q=10\] and also \[\left| p \right|{{\sigma }^{2}}=\left| p \right|\cdot 2=1\Rightarrow p=\pm \frac{1}{2}\] If \[p=\frac{1}{2}\Rightarrow q=0\] (rejected) & \[p=-\frac{1}{2}\Rightarrow q=-20\]You need to login to perform this action.
