A consumer watchdog group estimates the mean weight of 1-ounce fun size candy bars to see if customers are getting full value for their money. A random sample of 40 bars is selected and weighed, and the group reports that a 95% confidence interval for the true mean weight of the candy bars is 0.994 to 0.998 ounces. What is the margin of error?
