Battle of the sexes: Who gets pulled over more?

Background Research

We started by trying to find out if there was a previous study about this topic.  We went to www.google.com and typed in "men vs women driving violations" and it supplied us with numerous sites to choose from.  We clicked on the site http://editorial.autos.msn.com/article.aspx?cp-documentid=788126 and saw that there was a previous study about how men and women fared with driving violations.  This showed us that men were pulled over a lot more than women in every category of driving, such as reckless driving, DUI, seatbelt violations, speeding, failure to yield, and stop sign/signal violations.  The ratio of being pulled over for M:F for reckless driving was 3.41.  The ratio of being pulled over for M:F for DUI was 3.09.  The ratio of being pulled over for M:F for seatbelts violations was 3.08.  The ratio of being pulled over for M:F for speeding was 1.75.  The ratio for being pulled over for M:F for failure to yield was 1.54.  And the ratio of being pulled over for M:F for stop sign/signal violations was 1.53.  After using this site, we then went to the third site that was supplied to us to see what other studies there are.  The site http://www.qualityplanning.com/news/2008-articles/men-break-more-traffic-laws,-drive-more-dangerously-than-women,-concludes-qpc-study-.aspx also has the exact same information as the first site, which means that the information given is valid.  After we were done using this information, we then typed in "men vs women car crash statistics."  We used the fifth link that if supplied us with which led us to the website http://www.statisticbrain.com/male-and-female-driving-statistics/.  We wanted to see what gender got into car crashes more to solidify our views on which gender is a worse driver.  This showed us that men from the ages of 16-19 for every 100 million miles driven got into a fatal car crash 9.2 times, and females only 5.3 times.  For men from the ages 20-29 for every 100 million miles driven got into a fatal car crash 4.0 times, and females only 2.0 times.  For men from the ages 30-59 for every 100 million miles driven got into a fatal car crash 1.8 times, and females only 1.3 times.  For men of the age 70+ for every 100 million miles driven got into a fatal car crash 4.1 times, and females in this one were very close with 4.0 times.  The total amount of times that men get into fatal car crashes every 100 million miles driven was 2.5 times, and for females it was 1.7 times.  We can conclude from all of the data that we obtained from previous studies that men for the most part seem to be worse drivers then women.
