Answer: The margin of error is 12.74.

Step-by-step explanation:

Since we have given that

Standard deviation = 6.5

Mean = 255

Let 95% level of significance,

So, z value = 1.96

We need to find the "Margin of error":

So, it becomes :

Margin of error = Standard deviation × z-value

Margin of error = 6.5\times 1.96=12.74

Hence, the margin of error is 12.74.
