Thanks for those who replied. I know what a p-value is and the links given reaffirm my understanding. The code below gives p=0.26. This is more than 0.05 - hence null hypothesis i.e. attributed by chance. But I did not specify the significance level at 0.05. So I'm wondering if any part of the code states so. Or does R define significance level at 0.05 by default?
That's why you have been told to read what a p-value is! It is independent of the level of significance (which is not true for critical values). Just compare.
