A researcher is interested in studying how exposure to blue spectrum light (the light emitted from smartphones and other technology devices) can influence sleep quality. She randomly assigns one group of participants to use no technology before bed for 1 week, and a second group of participants to look at a smartphone or tablet for 1 hour before bed for 1 week, and a third group to read a book for 1 hour before bed for 1 week. She compares the groups on their sleep quality and expects that the group that uses technology before bed will sleep significantly worse than the other two groups

What is the alternative hypothesis for scenario 5?
