The correct hypothesis for the test made in this problem are given by:
H0: p = 0.25, Ha: p > 0.25.
At the null hypothesis, we test if the researcher is not correct, that is, if the proportion is of 25%, hence:
[tex]H_0: p = 0.25[/tex]
At the alternative hypothesis, we test if there is enough evidence for the researcher's claim, that is, if the proportion is greater than 25%, hence:
[tex]H_a: p > 0.25[/tex]
Hence the correct option is:
H0: p = 0.25, Ha: p > 0.25
