All are true about P-value except-
<p> Is equal to 1-ss. Type 1 error is usually fixed in advance by the choice of level of significance employed in the test. Power of a test:1-ss -is probability of rejecting a null hypothesis when a predetermined clinically significant difference is indeed present. -power can be increased by increasing the no. of subjects in a trial.

It is the probability of committing type I error
I s equal to I-ss
Is the chance that the presence of difference is concluded when actually there is none
When p-value is less than a, the result is statistically significant
