A researcher is interested in assessing the relationship between depression and anxiety. A group of individuals completed a depression inventory and an anxiety questionnaire. Higher scores on both assessments indicate a higher level of depression or anxiety. Test the relationship between these scores using a two-tailed test, α=.05. What is the verbal research hypothesis (H1)?

a. Neuroticism scores and hours spent on Instagram daily are linearly related; the correlation is not zero.

b. Neuroticism scores and hours spent on Instagram daily are not linearly related; the correlation is zero.

c. Neuroticism scores and hours spent on Instagram daily are negatively related.

d. Neuroticism scores and hours spent on Instagram daily are positively related.

Answer #1

As we are testing here whether Higher scores on both assessments indicate a higher level of depression or anxiety, therefore we are testing here whether the two variables are positively related or not. Therefore the null and the alternative hypothesis here are given as:

H0: The Neuroticism scores and hours spent on Instagram are not related

Ha: The Neuroticism scores and hours spent on Instagram are positively related

Therefore d is the correct answer here.
