I have no idea what "Ymin and found out that it equals 1" means
Why don't you write down what you found for the density of the smallest order stat.
Let Ymin be the smallest order statistic in a random sample of size n drawn from the uniform pdf f(y; theta) = 1/theta on the interval y is greater than 0 adn less than theta. Find an unbiased estimator for theta based on Ymin.
Okay so I started with the formula for Ymin and found out that it equals 1. The textbook also gave an unbiased estimator for theta that was equal to : (2/n) times the summation of Yi from i runs 1 to n.
This is where I get lost. How do I relate the single Ymin value to the given unbiased estimator for theta. Any tips for starting out would be great.
