Test for average weight of babies
We'll wrap up inference on a single parameter of a numerical distribution by revisiting the ncbirths dataset, specifically the weight variable, indicating the birth weight of the baby. Do these data provide convincing evidence that the average birth weight of babies born in North Carolina is different than 7 pounds?
