**Null Hypothesis Identification:** **d. Which of the following is the appropriate null hypothesis? Circle one.** - **A.** There is an association between a person’s sex and the number of Facebook friends. - **B.** There is no association between a person’s sex and the number of Facebook friends. - **C.** On average, men have more Facebook friends than women. - **D.** On average, men have fewer Facebook friends than women. *The null hypothesis typically states that there is no effect or no relationship.* --- **Alternative Hypothesis Identification:** **e. Which of the following is the appropriate alternative hypothesis? Circle one.** - **A.** There is an association between a person’s sex and the number of Facebook friends. - **B.** There is no association between a person’s sex and the number of Facebook friends. - **C.** On average, men have more Facebook friends than women. - **D.** On average, men have fewer Facebook friends than women. *The alternative hypothesis suggests there is an effect or a relationship.* --- *Note: Understanding how to choose the correct null and alternative hypotheses is crucial in statistical analysis. The null hypothesis usually indicates no change or no difference, while the alternative hypothesis suggests a potential difference or effect.*
