State the null hypothesis for this study. . (1m) You can reject Ho based on sig. value but the value of r is a weak one. How can you explain that? (2m) ili. How do you conclude this result? (3m) iv . Based on this position, write the likely regression equation. (2m) v. Write down statistics representation of the correlation in APA format.
