 The observed significance level is the chance of getting a
test statistic as extreme as or more extreme than the
observed one.  The chance is computed on the basis that the
null hypothesis is right.  The smaller this chance is, the
stronger the evidence against the null. 

 	
 The observed significance level gives the chance P of getting
evidence against the null hypothesis as strong as the
evidence at hand - or stronger.  It does not give the chance
of the null hypothesis being right.  In fact P is computed on
the basis of the null hypothesis.
