Meanwhile, we need to know the data of the sample mean, the standard deviation and the level of significance before we can state the appropriate hypotheses for this test.
Step-by-step explanation:
Given that:

Null hypothesis
Alternative hypothesis
The degree of freedom df = n -1
df = 300 - 1
df = 299
