Answer:

The margin of error of the sample mean is 0.648.

Step-by-step explanation:

The standard error(margin of error) of a sample mean is given by the following formula:

SE = \frac{s}{\sqrt{n}}

In which s is the standard deviation of the sample and n is the size of the sample.

In this problem, we have that:

s = 5.8, n = 80

So

SE = \frac{5.8}{\sqrt{80}} = 0.648

The margin of error of the sample mean is 0.648.

5.8/ sqrt 80=0.648 I think you are asking for the standard margin 
Hope this works
