I have done part one and found that the bias is [tex]\frac{\theta}{n}[/tex]

then i don't know how to proceed.

in my notes, have the following result,

i am thinking, this time i have to find the bias in [tex]\hat{\theta^*}[/tex]

then, if i work through, i got it's unbiased...

am i doing something wrong?

I am confused with that, the result in my notes, is it for the mean of the sample?

but here, we are aksed for the population variance?

Thanks
