One of the reasons why fewer women run businesses (at least as far as small businesses go) is that women are naturally more risk averse. Starting a business takes on a huge amount of risk. Some women are willing to deal with that, but statistically, it's not as common as it is for men. Men are generally a lot less worried about risk. The positive side of this is that some of them successfully run businesses of their own. The negative side is that men also die a lot more often in the workplace and tend to get injured more often there as well. And of course, most business owners that are currently running a successful business have already tried and failed multiple times with previous businesses. So, it takes a specific kind of mindset for someone to be successful at running a business. This acceptance of risk and multiple failures is not common among women. Women usually favor stability over risk, but of course, there are exceptions to this.
