<p><span style="font-size: medium;">A population has a mean «math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mi»§#956;«/mi»«mo»=«/mo»«mn»100«/mn»«/math» and a standard deviation of «math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mi»§#963;«/mi»«mo»=«/mo»«mn»15«/mn»«/math». Find the mean and standard deviation (standard error of the mean) of the sampling distribution of sample means with a sample size «math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»1000«/mn»«/math».</span></p> <ol> <li>«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«msub»«mi»§#956;«/mi»«mover»«mi»x«/mi»«mo»§#175;«/mo»«/mover»«/msub»«mo»=«/mo»«mo»§#160;«/mo»«/math»{1:NM:=100}<br /><br /></li> <li>«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«msub»«mi»§#963;«/mi»«mover»«mi»x«/mi»«mo»§#175;«/mo»«/mover»«/msub»«mo»=«/mo»«mo»§#160;«/mo»«/math»{1:NM:=0.474:0.001}</li> </ol>
