Twenty children are selected for a study on daily soda and milk consumption. The differences in consumption (Soda minus Milk) have a mean of 20 ml with a standard deviation of 33 ml.

We would like to construct a 95% confidence interval for the true mean difference in daily consumption of soda and milk. What is the margin of error for the confidence interval?

Keep 4 decimal places in intermediate calculations and report your final answer to 2 decimal places.
