When testing hypotheses, im having a hard time with the conclusion.

I can get the p-value, but my book says if you have a low pvalue, you reject the null. For example,

Trying to see if there is a homefield advantage..

Ho : p=0.50

Ha : p>0.50

P value < 0.0001

If the true proportion of home team wins were .50, then the observed value of .5496 would occur .0001

My book says since it is so low, you reject Ho.

This seems backwards to me, can someone explain?
