    likelihood ration test question

    How do I show that a likelihood ratio test depends on data only through the value of a sufficient statistic? I am not sure how to show this, even though it seems obvious. Since L(\omega_{0}) is the maximum of the likelihood function for all values of \theta in \omega_{0} isn't is clear that...

    Ration expression word problem please help!

    Jay Flew his airplane 500km against the wind in the same time it took him to fly 600km with the wind. The speed of the wind was 20km/h. What was the average speed of the airplane? I use S as the speed of the airplane I got 500/s-20km per hour = 600/s+20km per hour, but could get no...

    With randomized LR ration tests, how to show power increases with sample size.

    The questions states that if randomization is permitted, most-powerful alpha sized likelihood ratio tests based on X1,...,Xn have power non-decreasing in n. I have no idea how to show this. Any help is greatly appreciated.
