Question

Scenario: A high school teacher wants to examine whether playing sports affects attendance. She finds that the research is contradictory - some research suggests it may improve attendance, as students must attend class to play in their sport, but other research suggests it may result in more missed days, because students stay up late traveling to games and/or miss due to sporting events. What is the null hypothesis in this scenario? What is the alternative hypothesis in this scenario? What is the symbolic notation for this alternative hypothesis? Is this one or two tailed?
