Which of the following would be an appropriate alternative hypothesis?
A) The population mean is equal to 3.4.
B) The sample mean is greater than 3.4.
C) The population mean is greater than 3.4.
D) The sample mean is equal to 3.4.
E) The sample mean is not equal to 3.4.

Without knowing the specific problem, it is difficult to say.
The null hypothesis (Ho) would indicate that the two values were equal. Depending on how the specific problem is stated, the answer for the alternative hypothesis (H1) could be B, C or E.
I hope this helps. If not, repost your question with adequate data.
