State the null hypothesis for the research question: "Are female students more active on myUnisa than male students?"

The research question is: "Are female students more active on myUnisa than male students?"

A null hypothesis ($H_0$) is a statement that there is no statistical significance between the two variables in the hypothesis. It states that there is no effect, no difference, or no relationship. The research question asks if there is a difference in activity levels between female and male students. Therefore, the null hypothesis would state that there is no difference.

Let's evaluate the options:

• a. "There is a relationship..." This suggests an alternative hypothesis.
• b. "There is a difference..." This suggests an alternative hypothesis.
• c. "There is no difference between female and male students on their activity on myUnisa." This aligns with the definition of a null hypothesis, stating no difference between the groups being compared.
• d. "There is no relationship..." While a null hypothesis, the research question specifically asks about "more active," implying a comparison of activity levels, which is best captured by "no difference."

The correct option is c.

The null hypothesis would be:

c) There is no difference between female and male students on their activity on myUnisa.
