Did Ask Marilyn get it wrong this time?

Asked by LostInParadise (32183

I regularly read the Ask Marilyn column in the Parade magazine supplement. I remember the controversy surrounding her perfectly correct answer to the Monty Hall problem. This week she was given a much more elementary probability problem I was really surprised by her answer and agree with the person’s criticism. How can one account for this?

I got a chance to read a peer-reviewed journal-published paper, sciency stuff. And the data in the main table – which was the point of discussion of the entire article – had a column where the presented average was greater than any of the contributing amounts. It was impossible on the face of it, but no one even looked apparently.
