E = 0.028

Step-by-step explanation:
$E\text{ = 2 }\sqrt[]{(0.286(1-0.286))/(1041)}$

simplifying:

$\begin{gathered} 1\text{ - 0.286 = 0.714} \\ \\ E\text{ = 2 }\sqrt[]{(0.286(0.714))/(1041)} \\ E\text{ = 2 }\sqrt[]{(0.204204)/(1041)} \\ E\text{ = 2 }\sqrt[]{0.000196} \end{gathered}$
$\begin{gathered} E\text{ = 2 }*\text{ 0.0140} \\ E\text{ = 0.028} \end{gathered}$
