It is known that the amount of water adults drink per day follows a normal distribution with standard deviation 250 ml. A random sample of 50 adults is selected and it is found that their mean daily water intake is 1725 ml.

What is the margin of error for a 95% confidence interval for the true mean daily water consumption of adults? (You do not need to calculate the confidence interval. The margin of error is simply the right side of the ± sign in a confidence interval.)

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