I have to say if my correlation is significant or not so I did a ttest but I don't know what to do with the outcome. I calculated my correlation using excel = 0,754651674 R= 0,754651674 R square= 0,569499149 variance 57% > strong connection Test statistic t = r/√1r²/n2 0,75/√1(0.75)²/402 = 6.90 I don't know what to do with the 6,90 outcome?

$\displaystyle t_{0.05, df=38} = 1.685954$; your correlation is significant at the 0.05 level.
