Answer:
Right tailed test
Step-by-step explanation:
The null hypothesis is:
![H_o: \mu \le 30](https://tex.z-dn.net/?f=H_o%3A%20%5Cmu%20%5Cle%2030)
The alternative hypothesis is:
![H_a: \mu > 30](https://tex.z-dn.net/?f=H_a%3A%20%5Cmu%20%3E%2030)
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.
