Final answer:
The incorrect statement in this study is about delivery decisions for disabled individuals, which is not mentioned in the summary statistics.
Step-by-step explanation:
The incorrect statement in this study is that delivery decisions for disabled individuals are made arbitrarily without their consent. The study mentioned is about the number of Cesarean sections performed by male and female doctors, not about the delivery decisions for disabled individuals. The summary statistics provided in the question do not mention anything about disabled individuals or their delivery decisions.
