The null hypothesis agrees that the results from a test do not differ from what is the average result.
Therefore, H₀ = "The average age of community college students is equal to 24.6 years."
This can also be written as μ = 24.6 (Null hypothesis)
On the other hand, the alternative hypothesis does not agree with the general result or in this case, the average age.
Therefore, H₁ = "The average age of community college students is not equal to 24.6 years."
This can also be written as μ ≠ 24.6. (Two-sided Alternative Hypothesis)
If one-sided, the alternative hypothesis can be μ > 24.6 or μ < 24.6.
