A teacher wants to investigate whether there is a difference between male and female students in the amount of time they spend studying for statistics. What was the statistical test used to analyze the data? Is this a one or two tailed test? Identify Ha and Ho for this study. Conduct the appropriate analysis. Should Ho be rejected?

"Was" implies that the test has already been designated. What was it? Where is the data?
However, I can tell you that:
Ho: female time mean = male time mean
Ha: female time mean ≠ male time mean
With those hypotheses, it would be a twotailed test.
