I believe the answer is:
1. Because both males and females have different lives expectancy, and the rate of conducting risky activities also different between the two genders.
On average, female lives around 4.6 years longer compared to the male counterpart. This happen due to both biological reasons and due to the fact that Men on average have a more physically dangerous occupations compared to women (the majority of Police , Firefighters , Construction workers , and Miners are men)
2. It would be male
On average, men tend to pay 20% more compared to women. This happen because the activities that preferred by the women tend to resulted in more injuries. The number keep getting larger as they both got older. Before 40, average women pay $ 315 while average men pay $ 385. After 40, average women pay $ 495 while average men pay $ 620
