Answer:

Right tailed test

Step-by-step explanation:

The null hypothesis is:

[tex]H_o: \mu \le 30[/tex]

The alternative hypothesis is:

[tex]H_a: \mu > 30[/tex]

This is a right-tailed test since the alternative hypothesis is greater than 30

Suppose the level of significance is 0.05 and we are given a p-value less than  0.05.

Then, we reject the null hypothesis.
