I have to following question:

The correct answer is: $0.015$

I know that the definition of the $p$-value is:

The $p$-value is the probability of getting the observed value of the test static or a value with even greater evidence against $H\_0$, if the hypothesis is actually true

or in formula form $P (T \ge t)$ 

I have the following questions:

* What are $T$ and $t$?
* I think that distribution is uniform, but how do I calculate the $p$-value

Can I get feedback?
