<PRE><B>Question 933455</B>
SE = standard error = standard deviation of the sampling distribution


{{{SE = sigma/sqrt(n)}}}


{{{SE = 1.1/sqrt(200)}}}


{{{SE = 0.07778174593052}}} Use a calculator here. This is approximate.


{{{SE = 0.078}}} Round to the nearest thousandth


The answer is approximately &lt;font color=&quot;red&quot;&gt;0.078&lt;/font&gt;
