Has anyone done the case study in statistics for birth weigthts in America. Unable to determine which formulas to use for questions

Someone does not need to have done this case study to help. If you have a file of the statistics that you can upload or a link to a website that contains this information, then you can still ask whatever questions you have about it.

Depending on the questions, someone also might be able to tell you a formula without seeing the actual information.
