Question 990736: Four roommates (n=4) each contribute an average of $50 (M=50) towards buying a new table for their apartment. If one roommate who contributed $60 (X=60) decides to move out and not contribute any money, what is the value for the new mean contribution of the three remaining roommates? Answer by solver91311(24713) (Show Source):
Hint: If four people each contribute an average of $50 per month, then the monthly payment must be $200. The amount currently contributed by the roommate who is moving out is immaterial. There are now three contributors and they must, in toto, pay $200/month.
