It can be shown that\(\style{font-family:Times New Roman;}{\mu_{{\widehat p}_1-{\widehat ...

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 $\style{font-family:Times New Roman;}{P_1-P_2}$ .

▸

$\style{font-family:Times New Roman;}{P_1-P_2}$ is used to estimate $\style{font-family:Times New Roman;}{{\widehat p}_1-{\widehat p}_2}$ .
