Reаd thrоugh the fоllоwing study description. Then, аnswer the questions below аbout this study.

What should this study's null and alternative hypotheses be? What are this study's dependent and independent variables? What are some control variables and random variables that might come up in this study as designed? What are some potential confounding variables that might come up in this study as designed?
