Answer:

1.06

Step-by-step explanation:

The margin of error can be calculated using the following equation:


\text{margin of error = z}\frac{s}{\sqrt[]{n}}

Where z is related to the 95% confidence interval. For 95%, z = 1.96

Then, replacing the values, we get:


\text{margin of error = 1.96}\cdot\frac{3}{\sqrt[]{31}}=1.06

Therefore, the margin of error is 1.06
