It can be shown that

​

\(\style{font-family:Times New Roman;}{\mu_{{\widehat p}_1-{\widehat p}_2}=P_1-P_2}\)

​

This means:



▸

\(\style{font-family:Times New Roman;}{{\widehat p}_1-{\widehat p}_2}\)is the same thing as\(\style{font-family:Times New Roman;}{P_1-P_2}\).



▸

\(\style{font-family:Times New Roman;}\mu\)is unbiased for\(\style{font-family:Times New Roman;}{P_1-P_2}\).



▸

\(\style{font-family:Times New Roman;}{{\widehat p}_1-{\widehat p}_2}\)is unbiased for\(\style{font-family:Times New Roman;}{P_1-P_2}\).
