Homework Statement
In a study to estimate the proportion of residents in a city that support the construction of a new bypass road in the vicinity, a random sample of 2025 residents were polled. Let X denote the number in the sample who supported the proposal. To estimate the true proportion in support of the plan, we can compute p =(X+sqrt(2025)/2)/2025. What is the bias of the estimator p?
Homework Equations
The Attempt at a Solution
I am not too sure how to find the bias, can someone tell me what formula I am looking for, or how I should start?
All I could find was on wikipedia that the bias is Expected value(θ' - θ). I am assuming θ' is 2025? How do I continue from here?
Thanks
