This is for a statistics project. We're comparing individual players' statistics on the Giants, Mets, Yankees, A's, Marlins, and Dodgers for the 2005 season. Specifically, how their salary correlates with two primary statistics (Batting Average and # of Wins). Where can we find the MEAN and Standard Deviation of these statistics within the major league for the 2005 season so we can calculate P-values and Z-scores/T-scores?

I notice that a solution can be given by x=x(min)+sqrt(-f(xmin))
this is where x(min) is the value of x where the function reaches its minimun value and f(xmin) is the function evaluated in xmin
and sqrt mean the square root of
can anyone turn this into the feneral formula for solving second order equation? (10points in it)
and by the way can anyone quote a demontration for the above?

I don't mean how do you solve it, or look a differential equation up in a book, I mean how do you formulate one from scratch? Please give an example of how you wold do this.

I lived in the Florida Keys, met my now-wife on the telephone through business dealings when she lived in Calgary Canada. After three months of a developing telephone relationship, I took a Greyhound bus for $100 from Big Pine Key, Florida to Brooks, Alberta to meet her for the first time. Her brother was leery of me, but lightened up when we discovered we shared the same birthday.

I would presume any two random people had a 1:365 chance of sharing the same birthday (maybe that's not right but it sounds right to someone who never took sadistics in college)... BUT....

Is it even POSSIBLE to calculate the stastical probability of this kind of thing happening, calculating in the chance that someone from Calgary would be interested in coming to work for a non-profit in Key West, and the romance developing, and the birthday thing?

I'm ALSO just trying to figure out if it's more likely that this was a random thing, or if it is more likely to have a Larger Intelligence behind it.
