Using the information in Exercise 5.45, assume that a couple who wanted a girl was randomly placed into either the treatment group (receiving the medical process described) or the control group (no treatment administered) in a test involving the medical procedure.
a. What is the couple’s prior probability for being in the treatment group?
b. The couple’s newborn child is a girl. Given this additional information, what is the revised probability that the couple was in the treatment group?
