Here is the problem:
A consumer organization estimates that the mean of 1 ounce candy bars to see if customers are getting full value of their money. A random sample of 25 bars is selected and weighed and the organization reports that a 90% confidence interval for the true mean weight of the candy bars is .992 to .998 ounces.
Find the point estimate and the margin of error.
I have no clue where to begin. I think the margin of error is 10% but for the point estimate, I've never seen it. I looked through my textbook and the examples they have do not include problems where they give you a range of values. Thanks again!
