How do I figure this out given the data?
Σ x^2 - [(Σx)^2/n)]?
x...............................y
2008....................240,300
2009....................246,000
2010....................220,000
2011....................215,000 Is it just [(2008^2)+(2009^2)+(2010^2)+(2011^2)]-[(2008+2009+2010+2011)^2/2]? Thanks for your help! I am studying for my Stats exam in 2 weeks, and I don't have a clue how to solve this :/, I don't have any figures to check to see if I am right or not!
