According to the situation described, the appropriate set of hypotheses for her significance test is given by:

What are the hypothesis tested?At the null hypothesis, it is tested if the proportion is still of 42%, that is:

At the alternative hypothesis, it is tested if the proportion is now lower, that is:

Hence, the the appropriate set of hypotheses for her significance test is given by:
