I need help with the exercise below:

To investigate the effect of a new vaccine, 150 out of 300 sick animals were given the vaccine and the remaining 150 were given nothing. After a while, 10 of those who were given the vaccine and 30 who were not given the vaccine died. In this case, assuming $\alpha=0.05$ can we say that the vaccine decreases the proportion of deaddeath? In addition what would the power of the test be?

I stated the hypothesis as follows:

$H_0: P_{vaccine}=P_{No-vaccine}$

$H_1: P_{vaccine} < P_{No-vaccine} $

What formula should I use for the test statistics?
